There are many places on the internet where you can get detailed information such as Mr. Do animals really change their behavior during a total solar eclipse?
It has been reported during many eclipses that many different animals are startled by totality and change their behavior thinking that twilight has arrived.
You can explore this yourself with your own pets, or by watching local wildlife, especially birds. What are "shadow bands? These are among the most ephemeral phenomena that observers see during the few minutes before and after a total solar eclipse. They appear as a multitude of faint rapidly moving bands that can be seen by placing a white sheet of paper several feet square on the ground.
They look like ripples of sunshine at the bottom of a swimming pool, and their visibility varies from eclipse to eclipse. The Sun, however, is hardly a "point source" and the patterns are more random than you might expect from diffraction effects. The simplest explanation is that they arise from atmospheric turbulence.
When light rays pass through eddies in the atmosphere, they are refracted. Unresolved distant sources simply "twinkle," but for nearby large objects, the incoming light can be split into interfering bundles that recombine on the ground to give mottled patterns of light and dark bands, or portions of bands. Near totality, the image of the Sun is only a thin crescent a few arc seconds wide, which is about the same size as the atmospheric eddies as seen from the ground. Bands are produced because the Sun's image is longer in one direction than another.
The bands move, not at the rate you would expect for the eclipse, but at a speed determined by the motion of the atmospheric eddies. Typically, how big a temperature drop do you get during a total solar eclipse? It would probably be equal to the typical daytime minus nighttime temperature difference at that time of year and location on the Earth. Because the patch of the shadow travels faster than the speed of sound, weather systems will only be affected very locally directly under the instantaneous footprint of the eclipse.
The main effect is in the "radiant heating" component which goes away suddenly at the moment of eclipse and produces a very fast temperature decrease. If the wind is blowing, your body probably exaggerates, by evaporative cooling, how large the actual temperature swing actually is. Can I photograph the eclipse with my smartphone? As for your camera, there is no valid reason why you would want to point your smartphone camera at the brilliant, un-eclipsed sun without putting a filter over the lens.
During totality, you do not need the filter, of course! Unless you have a telephoto lens for your smartphone, you will only be able to take unmagnified images of the eclipse in your sky. These photos can be very exciting because the field-of-view is large enough that you can compose the shot with your friends and local scenery in the shot, at the same time a recognizable, eclipsed sun during totality hangs dramatically in the darkened sky.
You will easily be able to capture with most smartphone cameras the darkened disk of the moon surrounded by a clearly recognizable bright solar corona.
Many examples of these kinds of wide-angle shots can be found on the Internet. To get around this, you need a telephoto lens for your smartphone. There are many styles of telephoto lenses for smartphones. They are often of low optical quality. The best lenses are rated as 12x and above, and come with their own smartphone mounting bracket.
At these magnifications, a tripod is essential because of camera jitter. The telephoto lens will give you enough magnification that you will clearly see some of the details in the bright corona. You should test your system by taking night-time photos of the moon so you understand how large and detailed the moon will appear in your shot.

My house uses solar panels for electricity. Will they work during the eclipse? As you get close to totality, you should be able to notice a power drop in the output of your panels, which will reach a minimum when the sun is in full eclipse, and then your power levels will recover as the moon moves away from the sun.
In fact, this may be a fun science project if you can get in touch with many people in other cities that also have solar panels they can monitor. Go for it!! When can I see the next total solar eclipse from North America?
The next total solar eclipse visible from the United States occurs on August 21, The track goes from Oregon at its start, and exits on the east coast near South Carolina. After that, the next one visible from the Lower will be on April 8, which will track northeast from Texas to Maine and cross the path of the eclipse near Carbondale, Illinois. Since , there have been 15 total solar eclipse paths that have crossed the path of the August eclipse. Calculations show that it will take about years for every geographic location in the Lower to be able to view a total solar eclipse.
When was the last solar eclipse seen from contiguous United States, and when will the next one happen? The last total solar eclipse viewed from contiguous United States was on Feb.
After the August total solar eclipse, the next annular solar eclipse that can be seen in the continental United States will be on October 14, which will be visible from Northern California to Florida.
Following this, we will have a total solar eclipse on April 8, visible from Texas to Maine. When were solar eclipses first predicted accurately? The Babylonians knew how to predict lunar eclipses with some accuracy, but solar eclipses are far more difficult because the 'footprint' on the Earth is only a few tens of miles across and requires arc minute positional accuracy and forecasting for any specific locale.
Apparently Thales, c. E, is credited with predicting a solar eclipse from knowledge of a previous eclipse and using the Saros cycle. He predicted the year, but not the month and the day. It wasn't until Ptolemy's time that solar eclipse forecasting became more accurate. What major cities are located along the path of totality for the August eclipse?
About what time of the day will the eclipse be visible? Here are the local mid-eclipse times for some of the major towns and cities along the path of totality: am Corvallis, Albany and Lebanon, Oregon. What public parks are along the path of totality? Although many of the areas covered by the path of totality are privately-held, many parks span the path and are open for visits, although you can expect that parking may be a serious problem!

According to a map in which the tracks of all total solar eclipses from to BCE have been overlain, there are two such areas; one in north eastern Colorado centered on Fort Morgan, and one in Nebraska centered near Lewellen, that have not seen a total solar eclipse in over years.
Each area is about 50 km across. What kinds of programs might I expect at science centers and museums? There will literally be thousands of different venues to choose from across the continental United States. Some will offer lectures about eclipses, safe locations for viewing, proper viewing glasses, and many may host a variety of podcasts and other social media opportunities. Because most locations will not have schools in session, your local museum will likely have a schedule of planned events to choose from.
Also check out your local amateur astronomer club, which will be especially active and will likely offer safe telescopic observing of the event. Have total eclipses ever been mentioned in popular songs? Total solar eclipses have, indeed, been a popular theme. Her lyric refers to the March 7, total solar eclipse, and this is the only known recorded song that mentions a specific eclipse.
This will make future historians very happy if they try to date when the song was written if no other records exist. This is kind of like what archaeologists do with Babylonian cuneiform eclipse records today. Time travel had not been invented yet. Many people went to view the eclipse in Cornwall, the only place in the UK to witness totality, with the BBC broadcasting from Cornwall's western end where the eclipse would come first.
Navigate the night sky with our practical astronomy guides approved by Royal Observatory astronomers. As always, with any observing event involving the Sun, it should never be looked at directly without the appropriate filters. The Royal Observatory will be live streaming the next solar eclipse in the UK on YouTube and Facebook, featuring state-of-the-art telescopes and expert commentary from Observatory astronomers.

Judges' comments: One thing you often notice during an eclipse is how quiet everything becomes. Solar eclipses are calm, serene moments. This stripped-back image captures that serenity perfectly.
The calm glow behind the silhouetted hills is all that is needed. Melanie says: A group of us went to Indonesia primarily to view the eclipse, but saw many other amazing things too, such as volcanoes and orangutans. We were very lucky. The wet weather cleared in the morning to reveal a hot sunny day, before cloud again came over towards the end of the eclipse. This was my first ever total solar eclipse, and so the first time I have ever taken a photo of it.
I am so glad I was able to take a picture of totality and the diamond ring. What an experience it was, one I most certainly will never forget. From Earth it seems like the sunlight seen around the edge of the Moon is broken into fragments because the uneven lunar surface obscures some of the light.
This creates the illusion of a string of beads encircling the Moon. NASA's Solar Eclipse Bulletins were special publications issued periodically that focused on major upcoming solar eclipses. Each bulletin contained detailed eclipse predictions, local circumstances, maps and climatological data along the eclipse path.
The NASA eclipse bulletins ended with the eclipse bulletin. All eclipse calculations are by Fred Espenak, and he assumes full responsibility for their accuracy.

This can only happen during a period of time that occurs a little less than every six months, and lasts, on average, around This period is called the eclipse season , and it is the only time that eclipses take place. The lunar nodes are the two points where the plane of the Moon's orbital path around Earth meets Earth's orbital plane around the Sun, the ecliptic. Even though solar eclipses occur every year, they are considered a rare sight, much rarer than a lunar eclipse.
This is because while a solar eclipse is only visible from a very narrow path on Earth, a lunar eclipse is visible from every location on the night side of the Earth while it lasts. On August 21, , a total solar eclipse was visible in a narrow track spanning the United States. This was the first total solar eclipse visible from anywhere in mainland United States since the total solar eclipse in February The next total eclipse in the US is in April
