Eclipse of April 8, 2024

2024 Eclipse Path. NOAA image.

As we did in 2017, OneTubeRadio.com will provide full coverage of the April 8, 2024, total solar eclipse.

This is exactly five years from today.  Little preparation is needed at this point, but you should make a mental note to travel to the path of totality, which is less than a days’ drive from most of the United States.  The total eclipse will be visible in parts of Texas, Oklahoma, Arkansas, Missouri, Illinois, Indiana, Ohio, a tiny piece of Michigan, Pennsylvania, New York, Vermont, New Hampshire, and Maine.  The path of totality also passes through Mexico and Canada.  Major cities in the path of totality include Dallas, Little Rock, Indianapolis, Buffalo, Cleveland, and Montreal.

The eclipse will take place on a Monday.  For the 2017 eclipse, we made our hotel reservations about a year in advance, and paid the normal rate with plenty of availability.  So if you plan on booking in April 2023, you should have many options.  Also, in late 2023 or early 2024, you should order your eclipse glasses.

If you have kids who will be in school, plan on taking them out of school that day.  Unfortunately, the 2017 eclipse showed that American schools had an irrational fear of the eclipse and actively prevented children from witnessing it.  If you believe that your child’s school is more enlightened, then on the first day of the 2023-24 school year, you should have your children ask the science teacher if the school is planning a field trip to see it.  If the teacher balks, then your children should let him or her know that they will be absent the day of the eclipse.

This is an entirely reasonable request for most schools.  For example, students in Chicago could be placed on a school bus and taken to see the eclipse only a couple of hours’ drive away in Indiana.  The expense will be less than other field trips taken to amusement parks, movies, etc.  This is true for schools in many cities.  They have the opportunity to let the kids witness an amazing scientific event, but only if they do some basic planning.

But I predict that this won’t happen, since most schools won’t think of the possibility until after it’s too late to make the necessary plans, or they’ll have the same irrational fears that showed up in 2017.  It’s the duty of the students to pester the administration so that the necessary plans are made sufficiently in advance.  And as I explained in 2017, if the school fails to act, then it’s reasonable for children to skip school on April 8, 2024.

 

 



Solar Eclipse of February 26, 1979

1979 eclipse 3.tif

Today marks the 40th anniversary of the solar eclipse of February 26, 1979.  The path of totality passed through Washington, Oregon, Idaho, Montana, and North Dakota before entering Saskatchewan, Manitoba, Ontario, Quebec, and the Northwest Territories. From Canada, the path of totality entered the north Atlantic before ending in Greenland.

The path through Winnipeg, Manitoba, was tantalizingly close to my home in Minnesota, but I was unable to travel to see the spectacle. I had to settle for 90% coverage (in other words, millions of times more sunlight) where I was. I did vow that I would see the next one, in 2017, and I did.

This video shows coverage of the eclipse as totality passed through Winnipeg:



Lunar Eclipse, January 20, 2019

While not nearly as spectacular as a solar eclipse, another interesting astronomical phenomenon will be visible this Sunday evening throughout the Western Hemisphere.  This will be a lunar eclipse, in which the moon passes through the shadow of the earth.

The eclipse begins at 9:36 PM Eastern Time (8:36 CST, 7:36 MST, 6:36 PST) with the penumbral phase, as the moon enters the outer shadow of the earth. The brightness of the moon will decrease, but the small change in brightness probably won’t be visible to the naked eye.

About an hour later at 10:33 PM Eastern Time (9:33 CST, 8:33 MST, 7:33 PST), the eclipse enters the partial stage. At this time, the earth’s shadow begins to eat away at the moon. This continues until 11:41 PM Eastern Time (10:41 CST, 9:41 MST, 8:41 PST), when the eclipse becomes full, and the moon is completely within the shadow of the earth.

Unlike a solar eclipse, the times are more or less identical wherever you are.  You only need to adjust for your time zone.

Image result for lunar eclipse site:nasa.govEven though the eclipse is full, the moon does not become fully dark. This is because the moon is illuminated by a ring surrounding the earth, namely, all of the sunrises and sunsets taking place on earth.

At 12:43 AM Eastern Time, the eclipse once again becomes partial. At 1:50 AM Eastern Time, it re-enters the penumbral phase. At 2:48 AM Eastern Time, the eclipse ends.

We previously wrote of an interesting story of a lunar eclipse of July 15, 1916. This eclipse affected the Shackleton Antarctic expedition. The team led by Aeneas Mackintosh was waiting for a full moon to embark, but were surprised to see the moon entering an eclipse as it rose. Fortunately, the eclipse was only partial and enough light remained to make the voyage.



NBC Radio, Canton Island Eclipse Coverage, 1937

1938Sep5LifeThis picture appeared in an RCA advertisement in Life magazine 80 years ago today, September 5, 1938. It shows NBC engineers Marvyn Adams and W.R. Brown along with NBC announcer George Hicks broadcasting live from Canton Island (sometimes spelled Kanton) in the South Pacific.

1937 Eclipse from Canton Island. Wikipedia image.

They were on the island as part of a joint expedition by the U.S. Navy and the  National Geographic Society for the solar eclipse of June 8, 1937.  The NBC eclipse coverage was transmitted from this “ultra-high frequency transmitter” to the USS Avocet anchored at the island, and from there to the RCA station at Point Reyes, California, where it went by wire to the NBC Blue Network.

According to the ad, the island would possibly “play an important role in transpacific air transport service,” a prophecy which proved true, as the island served as a stop for PanAm’s Pacific Clipper service to New Zealand, which ran from 1940 until the war, and then again from 1946.

The Navy-National Geographic expedition, in addition to observing the eclipse, placed a monument on the island to bolster the U.S. claim to sovereignty over the island. This was disputed by the British, who also had a ship anchored for the eclipse. Reportedly, the British ship, the HMS Wellington, fired a shot across the bow of the USS Avocet, which reciprocated. The two commanders called a truce pending further instructions from their command, and the two parties observed the eclipse together.

During the war, the U.S. Navy built a 6230 foot airstrip on the island, which was defended by as many as 1200 combat forces, but was never attacked by Japan.  The island now forms part of the Republic of Kiribati.  As of 2010, it had a population of 24.

The island was most recently in the news that year after a yacht stopped en route from Honolulu to Fiji and discovered that the islanders were desperately short of food, an expected supply ship never having arrived.  The islanders had been living on fish and coconuts for several months, and the yacht owner used his satellite phone to contact the U.K. Coast Guard, which contacted the U.S. Coast Guard to arrange relief supplies.



1952 and 1954 Solar Eclipses

SovietEclipseCoverMillions of Americans were able to witness the Great American Eclipse of 2017 or will be able  to see the eclipse of April 8, 2024.  The 2017 eclipse crossed the United States from northwest to southeast, and the 2024 eclipse will run from southwest to northeast.  The Soviet Union had a similar pair of eclipses on 25 February 1952 and 30 June 1954.  The intersection of the two American eclipses is near Carbondale, Illinois.  The paths of the two Soviet eclipses had their intersection at a point in northern Iran, just south of the Caspian Sea.

SovietEclipseMap

The illustrations shown here are from a Soviet booklet published in 1950.  In addition to discussing solar and lunar eclipses generally, it contains information about the two Soviet eclipses of the 1950’s, including the map shown above.  It also contains a table showing all total solar eclipses worldwide through 1999.

The booklet, Солнечные и лунные затмения (Solar and Lunar Eclipses) by Prof. A.A. Mikhailov, part of the series Научно-популярная библиотека (Popular science library), reveals that the path of the 1954 eclipse came very close to a number of Soviet cities, including Kaliningrad, Vilnius, Minsk, Kiev, Rostov, and Baku.   The 1954 eclipse had also been visible in the United States, starting at sunrise in Nebraska, and passing over South Dakota and Minnesota (including Minneapolis and St. Paul).  It then passed over Canada, Greenland, a tiny portion of Iceland, Norway, and Sweden, before entering the Soviet Union near Kaliningrad.

The 1952 eclipse, after passing over Africa, went over a less populated area of Turkmenistan, Uzbekistan, Kazakhstan, and Asiatic Russia.

This video shows the 1954 eclipse from Minneapolis:

This page contains a reminiscence and photo of the same eclipse from Kiev.  The Google translate function does an admirable job of making it readable in English.

One of the scientific observations made during the 1954 eclipse was the measurement of radio emissions by the sun on various frequencies, documented in this 1955 article in the journal Astrophisica Norvegica, vol. 5, p. 131.  The graph below shows the signal as received in Vesterøya, Norway, on 200 MHz.  As would be expected, the solar noise reaches a minimum value at the time of total eclipse.

What to Do With Your Used Eclipse Glasses

Now that the eclipse is over, you probably have eclipse glasses that you don’t need. You might want to save at least one pair, since you can use them to view sunspots, to view the transit of Mercury* on November 11, 2019, or even to view the International Space Station when it crosses in front of the sun*. You can also save them, of course, for the next eclipse in 2024.

  • Update:  See the important note at the end of this post before attempting to view the transit of Mercury or the transit of the ISS. 

However, you might want to get them into the hands of someone else who can use them to view an eclipse. One option is to send them to Astronomers without Borders, which is collecting used glasses, and will distribute them to persons in other parts of the world before upcoming eclipses. You can find instructions at their website.

However, you can just as easily cut out the middleman. Astronomers Without Borders will need to sort the glasses and distribute them. You can just as easily send them directly to someone who can use them. It will only cost you $1.15, which is the international postage rate for up to one ounce, which is enough for two sets of glasses and a letter explaining what they are.

Coverage of eclipse of 15 Feb. 2018. Wikipedia, by Fernando de Gorocica – Own work, CC BY-SA 4.0.

The next eclipse will take place on February 15, 2018. This will be a partial eclipse that will be visible in Chile and Argentina. It will just barely be visible in Buenos Aires, but the sun will be about 40% covered in southern Chile and Argentina, in Tierra del Fuego.

Argentina and Chile will also have two total eclipses, in 2019 and 2020. Therefore, it makes sense to get students in southern Argentina and Chile excited about the partial eclipse in February. After they see the partial eclipse in 2018, they will have time to make plans to go see the total eclipses in 2019 or 2020, just like we did in 2017.

It’s not hard to do. All you need to do is find the name and address of a school in southern Argentina or Chile. Then, you send them one or two pairs of glasses, along with a letter explaining what the glasses are for.

Here’s a sample letter in Spanish.  You can simply cut and paste this letter into your word processor.  If you want, you can add your name, address, and e-mail.  Or if you prefer, you can just send an anonymous gift.

Estimados [NAME OF SCHOOL]:

Encontré su nombre y dirección en Internet, y me gustaría presentarle este pequeño regalo. Éstos son lentes especiales que se pueden utilizar para ver con seguridad el sol durante un eclipse solar.

Hubo un eclipse solar total en los Estados Unidos el 21 de agosto de 2017, y vi esta espectacular vista en el estado de [STATE WHERE YOU SAW THE ECLIPSE]. No habrá otro eclipse solar en los Estados Unidos hasta 2024. Habrá eclipses en Argentina y Chile en 2018, 2019 y 2020. El proximo eclipse, un eclipse parcial, será el 15 de febrero de 2018 en el sur de Argentina y Chile. Por lo tanto, los estadounidenses han sido alentados a enviar sus gafas de eclipse a escuelas u organizaciones en Argentina o Chile. Estos lentes se volvieron difíciles de encontrar en los Estados Unidos antes del eclipse, y queremos asegurarnos de que tantas personas como sea posible tengan gafas para ver los próximos tres eclipses.

Hay más información sobre el eclipse y sobre estas gafas en el siguiente sitio de internet:

http://OneTubeRadio.com/gafas/

Esperamos que disfrute viendo los próximos eclipses tanto como disfrutamos del nuestro.

En amistad,

Here’s a translation in English:

Dear [NAME OF SCHOOL]
I found your name and address on the internet, and would like to present you with this small gift. These are special glasses that can be used to safely view the sun during a solar eclipse.

There was a total solar eclipse in the United States on August 21, 2017, and I viewed this spectacular sight in the State of [STATE WHERE YOU SAW THE ECLIPSE]. There will not be another solar eclipse in the United States until 2024. There will be eclipses in Argentina and Chile in 2018, 2019, and 2020. The next eclipse, a partial eclipse, will be on 15 February 2018 in the south of Argentina and Chile. Therefore, Americans have been encouraged to send their eclipse glasses to schools or organizations in Argentina or Chile. The glasses became hard to find in the United States before the eclipse, and we want to make sure as many people as possible have glasses to view the next three eclipses.

There is more information about the eclipse and about these glasses at the following website:

http://OneTubeRadio.com/gafas/

We hope you enjoy viewing the next eclipses as much as we enjoyed ours.

In friendship,

Or, if you prefer, you can write your own letter, either in English or Spanish.  Even if your letter is in English, someone will be able to read it.  The letter includes a link to a page on this site, and that page includes more information in Spanish, along with links to other sites with information about the upcoming eclipses.

It’s easy to find the name of a random school to send the glasses to.  Just go to Google Maps, and zoom in on southern Argentina or Chile.  Find the name of a town.  Then, Google the name of that town along with the word “escuela” or “colegio.”  Look through some of the results, and you’ll find the website of a school.  Look for their address on their website.  Put the glasses in an envelope with $1.15 postage, and put them in the mail.

A high school in Arkansas also needs a few samples of various brands of eclipse glasses.  You can see more details at this Facebook post to see if they still need a sample of your brand.


Update:   I’ve been informed that it’s not possible to see the transit of Mercury or the transit of the ISS with the naked eye.  Of course, it doesn’t hurt to try, as long as you have your trusty eclipse glasses on.  But whatever you do, don’t try to kludge something together to use binoculars or a telescope in conjunction with your glasses.  If the glasses are at the end near your eyes, then there’s a real possibility that the magnified rays of the sun will burn a hole in the glasses, followed quickly by a hole burnt into your eyeball, which is not a good thing.  Putting the glasses on the other end of the telescope or binoculars isn’t quite as dangerous, but it’s still a really bad idea.

The person who brought this to my attention was concerned that someone would attempt to do these things, that they would do them in an unsafe manner, and they would then sue me.  You can, of course, sue anyone at any time for any reason.  But the lawsuit would almost certainly be unsuccessful, as explained in this case.



Post-Eclipse Report

Minutes after totality.

Minutes after totality.

The total solar eclipse was awesome, and well worth the trip to Hastings, Nebraska!

Travel Report

We left Minnesota on Saturday and drove to Fremont, Nebraska.  The traffic was noticeably heavy on both Interstate 35 and Interstate 80.  Many of the vehicles we saw were obviously eclipse chasers, with cars packed full of camping gear.  The heavy traffic was very apparent when we turned off onto I-680 to get to our hotel room in Fremont.  That highway was deserted, which appeared all the more eerie after witnessing the extremely heavy traffic directly on the route to the path of totality.  On Sunday, traffic was heavier still as we moved back onto the interstate, but was still moving at posted speeds.

We were in position by Monday, so we didn’t experience traffic the day of the eclipse.  It was reported to be heavy, but with no major delays.  The only eclipse-related traffic issue was an announcement on the radio that the Nebraska Highway Patrol had closed both I-80 rest areas near Grand Island for safety reasons.  Gasoline and other supplies were readily available at normal prices.

According to reports, traffic was heaviest after the eclipse as hundreds of thousands of visitors headed home.  Still, no major issues were reported, and traffic, while somewhat slower than normal, was moving along well.  We drove home Tuesday.  While traffic appeared normal by the time we were on the road, many cars were obviously those of other eclipse chasers, as evidenced by the camping gear filling many of them.

Viewing the Eclipse

The eclipse in Grand Island. NBC Nebraska.

The eclipse in Grand Island. NBC Nebraska.

On Monday morning, we set up in American Legion Park in Hastings, a small city park just across the street from our hotel.  Other viewing areas were packed, but we shared the park with only about a dozen other visitors, mostly from Minnesota, Wisconsin, and Iowa.   There were street lights on the neighboring road, but we stayed clear of them and they didn’t present any obstacle to our viewing.

We didn’t bother trying to take photos of the eclipse.  We only had two minutes, so rather than fiddling with cameras during that time, we simply enjoyed the spectacle and left the photography to professionals.

The best representation I’ve seen so far of what we experienced is from NBC Nebraska at this link.  if you click on Part 3 of the video at that link, and then advance to the 4:00 minute mark, you’ll see a live report from a Middle School in Grand Island, about 20 miles north of where we were.  The video does a good job of capturing the darkness of the sky, as well as the reaction of those present.  The video doesn’t do justice to the corona itself, but all of the other elements reflect very well what we witnessed.

It’s also evident from the video what I kept saying before the eclipse: The eclipse was something that kids needed to see!  The reaction of the middle school kids in this video was overwhelming, and the eclipse is something that they will never forget.  It’s a shame that some schools locked their kids inside rather than taking them to see it.  There are now undoubtedly many future astronomers and scientists among the kids in Grand Island and other places where enlightened educators made it a unique learning experience.  The kids who were left inside for the eclipse did not get that inspiration, and any school administrators who took that approach should be ashamed of themselves.

In Hastings, there were thin scattered clouds throughout the morning.  However, with the cooling caused by the eclipse, the sky was clear during totality, the clouds not reappearing until about 10 minutes later.   It was noticeably cooler starting a few minutes before totality.  Even though the surroundings were not noticeably dimmer to the human eye until just before totality, the direct sunlight didn’t feel warm as it had in the morning.

We saw the diamond ring both before and after totality.  I did not see Bailey’s Beads, nor did I see any shadow bands.  The horizon in all directions had the orange glow of sunset.  Venus was plainly visible.  I didn’t notice it before totality, but it persisted for a couple of minutes after the sun returned.

Radio Experiments

EclipseQSOPartyAs shown here, I was doing my part for science by operating in the HamSci Solar Eclipse QSO Party.  Along with other amateur radio operators, I was operating in this event to generate data which researchers will use to understand the ionosphere and how it was affected by the eclipse.  Radio signals are reflected by the ionosphere, and the effect varies depending on frequency, and depending on the amount of solar energy hitting the ionosphere.  The eclipse gave a rare opportunity to show the effects when the amount of solar energy varies over small areas, such as the path of totality.  I concentrated mainly on making short transmissions to be picked up by remote receivers.  Some of these receivers are connected in real time to the Reverse Beacon Network, which displays received signals almost immediately on the Internet.  Unfortunately, my signals were not picked up by these stations, but other software-defined receivers were continuously recording the radio spectrum, and it’s likely that my transmissions were recorded and will be available at a later date.

I didn’t spend much time trying to make two-way radio contacts, but I did make three contacts, which are shown on this map:

seqpmap

All three of these contacts were made before totality.  I was operating on the 40 meter band (7 MHz) with only 5 watts of power, and the distances of these contacts does seem much greater than would normally be expected that time of day.  The most distant contact was with WA1FCN in Cordova, Alabama, 776 miles from my location in Hastings, Nebraska.  We made this contact at 12:29 PM local time, about 30 minutes before totality.  It seems likely that this contact was possible only because of the eclipse.  The contact with N5AW in Burnet, Texas, 680 miles away, was made at 12:10 local time, and the contact with W0ECC in St. Charles, Missouri, 438 miles away, was made at 11:08 local time.  In all three cases, the partial eclipse was underway at both locations when we made our contacts.

The HamSci researchers at Virginia Tech will have a lot of data to analyze, but I think it’s clear that the eclipse was having an effect on propagation.  The 40 meter band is generally limited to shorter distances during the day, and the path lengths here seem more consistent with the type of propagation normally seen in the evening.

For those who are interested in the details, my station consisted of my 5 watt Yaesu FT-817 powered by a 12 volt fish finder battery.  The antenna was a 40 meter inverted vee with its peak about 15 feet off the ground, supported by my golf ball retriever.  The two ends of the antenna were supported by tent stakes in the ground.  The station was similar to what I used in 2016 for many of my National Parks On The Air activations. The antenna was running north-south in an effort to have its maximum signal along the east-west path of totality.  Since the antenna had an acceptable match on 15 and 6 meters, I also made a few test transmissions on those bands, although I concentrated on 40 meters.

Nebraska and the Eclipse

The State of Nebraska, the City of Hastings, and all of the other towns we encountered along the way, did an excellent job of planning for the eclipse and accommodating all of the visitors.  While traffic was very heavy, there were no real problems.  The staff of our hotel, the C3 Hotel & Convention Center, was extremely well prepared for what was probably the hotel’s busiest night ever.  The accommodations were excellent!

Since virtually all of the hotel rooms in the state were filled, dozens of temporary campgrounds sprung up, and visitors were able to find safe campsites at a reasonable price as homeowners, farmers, and ranchers opened their land for camping.

The only traffic-related problem that I’m aware of was the closure of two highway rest areas shortly before totality.  Unrelated to the eclipse, the City of Seward, Nebraska, experienced an ill-timed water main leak, leaving the city without drinking water during the eclipse.  We did see units of the Nebraska National Guard on the road, but as far as I know, other than to distribute drinking water in Seward, their services were not needed during the eclipse.

The entire state deserves high marks for its preparations in making the eclipse an unforgettable event for the hundreds of thousands of visitors.

Live Streaming the Eclipse by Morse Code & Other Eclipse Links

BrownEclipseSketchWe are now beginning our final preparations to activate the official OneTubeRadio.com Eclipse Headquarters in Hastings, Nebraska. On Saturday and Sunday, we will post updates, including reports of conditions along Interstate 80 as eclipse visitors pour into the Cornhusker State.

IonosphereDuring the eclipse, we plan to transmit radio signals that you can monitor in real time at home. I’ll try to repost it before Monday, but you will be able to follow in real time at this link.  I currently plan to transmit on 40 Meters (7 MHz).  Within seconds of each transmission, you will be able to see where the signal was picked up.  With normal conditions, most of that reception would be within about 400 miles.  As the partial eclipse begins in the west, I expect enhancement in that direction.  As the moon’s shadow moves toward South Carolina, I expect the signal to be enhanced toward the east.  You can watch these changes real time.  The cellular network could very well crash, but even if it does, you watch me in real time as I live stream via Morse Code.

That page will contain a map which will incorrectly show that my transmissions are originating from Minnesota.  However, the signals will originate in Nebraska, and the locations of the receiving stations on the map will be correct.

Here are links to other earlier posts:

  • Take Your Kids to See the Eclipse!  This is the biggest scientific event of your children’s lifetime.  You should take them to see it.  If you were close to Yellowstone National Park, you would want to take them.  If you were close to the Grand Canyon, you would want to take them.  This time, you are close to an equally important natural wonder.  And it will only be there one day.
  • Planning for Eclipse Gridlock.  In this post, I offered my predictions for eclipse traffic.  The news reports on Monday will let you know whether my predictions were right.
  • Eclipse Travel Recommendations for Minnesota and Iowa.  If you are reading this before Saturday, despite what you’ve heard, you can get an inexpensive hotel room close to the eclipse.  If you’re reading this over the weekend, it’s still possible to make a one-day trip to the path of totality.  It’s even possible to take a bus to see the eclipse.  This page has complete information for seeing the eclipse for those in Minnesota and Iowa, and much of the advice is relevant to those in other states.
  • Eclipse Campground List.  I’ve compiled this list of eclipse campsites coast to coast.  Most still have spots available.
  • Eclipse Radio Experiments.  At this page, I explain my radio experiments.  I also tell how you, and even your kids, can participate by “listening” to the eclipse on an AM radio, and submit those results for publication in Sky & Telescope magazine.



Win Free Eclipse Glasses!

This contest how now ended.  We are running a Facebook contest, and two lucky winners will receive a free pair of eclipse glasses.  The glasses are similar to the ones shown here, and are ISO and CE certified as safe for direct viewing of the sun.  They are made in the USA by American Paper Optics.  (I purchased them directly from American Paper Optics, and they were shipped to me directly, so there’s no chance that these are counterfeits.)

Most retailers have now run out of the glasses.  This might be your only chance to get them, and they won’t cost you a dime!

To enter, simply follow these two steps:

  1. “Like” us on Facebook. Just click on this link and then click the “Like” button near top of the page.  (If it says “Liked,” then you already have this step taken care of.)
  2. Go to the contest announcement, which is the pinned post at the top of that page. I have randomly generated a number between 1 and 200. Post your guess as a comment to that Facebook post.  The two closest guesses will be the winners. I will contact the winners for their mailing addresses.

The winners will be the two who posted the numbers closest to the secret number.  In case of tie, the earliest post(s) will win.

The contest ends at 11:59 PM Central Time on Monday, August 14, 2017.  I will contact the winners by Facebook message, and you will need to send me your mailing address.  I will mail them by First Class Mail on Tuesday, August 15.  Glasses will be sent folded in a normal business size envelope.

If you want to purchase eclipse glasses, please see my post with advice on where to find the few remaining pairs.  Click here for more eclipse information.

Alternatives to Eclipse Glasses

This page last updated Thursday, August 17.  It is now too late to get the glasses, but I list a number of alternatives that will work better.

Quick Links:

In most areas, it is now too late to get eclipse glasses at a reasonable price.  Just like happened during a recent eclipse in England, the glasses are now unavailable in most places.  They might be available in some areas at a reasonable price.  But don’t pay more than a few dollars, because you don’t need them.  If you don’t have them, don’t worry.  You can actually get a better view using other methods.

Whatever you do, don’t spend hundreds of dollars trying to find a pair.  They’re nice to have, but they are not essential.  You do have alternatives.   First of all, if you are around other people watching the eclipse, you can probably just borrow theirs.   You’ll only look through the glasses for a minute or two at a time.  Several people can use the same pair.

If you don’t have glasses (or even if you do, and want a better view, you can use a method of indirect viewing.

You can make a simple pinhole viewer, and instructions are available at the NASA website.  Many other variations are available, and you can get a  good view of the sun projected on a screen.

 

 

Other projection methods provide a view that is better than the eclipse glasses.  One extremely simple method uses binoculars or a small telescope or monocular.  (Use cheap binoculars, since the sun might overheat and damage them. Even toy binoculars like the ones shown here should work just fine.)  You do not look through the binoculars.  Instead, you point one end at the sun, and the other end at a white screen, or even the wall of a building.  You will see a very detailed image of the sun on the screen.  It’s amazingly simple, and you will see a much better view than you would with eclipse glasses.  It is described at this website.

Also, remember that eclipse glasses can be shared.  It’s somewhat interesting to look at the crescent sun, but most people will only look for a few seconds, and then possibly look again later when it’s gotten smaller.  In the meantime, others can use them.  If you are traveling to some kind of viewing event, it’s likely that other people will let you borrow their glasses.

 


Buying Online

Glasses are no longer available.  This page has been continually updated.  All of the websites listed below had glasses at a reasonable price.  As each one ran out, I removed the listing, and now it’s too late.

The following suppliers were previously listed here, but are now sold out:  American Paper Optics AmericanEclipseGlasses.comGreatAmericanEclipse.com and  Rainbow Symphony.  The GreatAmericanEclipse.com website remains an excellent source of information about the eclipse.  At this point, I do not recommend ordering from  Amazon, eBay, or other similar sites.  You will pay too much, they might not arrive in time, and the product might not be safe.


Local Retailers in Minnesota and Other Areas

Glasses are no longer available.  This page has been continually updated.  All of the stores listed below had glasses at a reasonable price.  As each one ran out, I removed the listing, and now it’s too late.  In some parts of the country, the situation might be different, and you might want to check some of these stores in your area.  In many cases, the link is to the particular set of glasses sold by that store.

The following retailers had glasses, but are now almost certainly sold out:  New York:  B&H Photo and Video.  Minnesota:  Radio City in Mounds View , Toys R Us,  Lowe’s, Walmart, AxMan SurplusGirl Scout Shop in St. PaulBest Buy .

Some public libraries were giving the glasses away free.  They are probably gone by now, but they might have some available at special viewing events.
