OnApril 8 , a total solar eclipsewill be visible in the skies above 15 U.S. country , as well as part of Canada and Mexico . Millions of viewers within thepath of totalitywill see eerie darkness in the daytime , while innumerable others will have a partial tone across that will be visible across the entire conterminous U.S.
Whether or not you design to see the total form of the occultation , it should still be prominent — and it may still have a few freaky effects . An occultation " is the most affected innate phenomenon you ’ll ever experience,“Tyler Nordgren , an astronomer , creative person and author who often work with the National Park Service , told Live Science in an interview . Here are a few of the weird thing that you might experience during asolar eclipse .
Baily’s Beads, total eclipse of the Sun, Turkey, 29 March 2006.
1. Baily’s beads
If you reckon a total solar occultation ( safely , with appropriate eye protective covering ) , you might notice a sliver of light around the moon ’s border that appears beaded , like a necklace . This phenomenon is know as " Baily ’s beads . " key out for astronomer Francis Baily , who described the consequence in 1836 , it is triggered by sunlight interacting with the moon ’s uneven topography .
2. Solar prominences
Solar prominences , also fuck as filaments , are hugeplasma - and - magnetised - plain structuresthat come up from the Lord’s Day ’s surface . unremarkably , we ca n’t see these protuberances from Earth . But during an eclipse , they may be seeable behind the moon , appearing like petals on a blossom .
A banker’s bill of caution : DO NOTlook for solar protrusion or Baily ’s astragal with your naked eye ! Always fatigue occultation glass .
3. Plunging temperatures
Bring a jacket to your occultation viewing , because temperature can cast off quickly as the moonlight cover the sunshine . How much depends on the location , meter of year and type of eclipse . Most places see temperature drops of around 5 to 10 degrees Fahrenheit ( 2.8 to 5.6 degrees Celsius ) during a total occultation , though the plunge can be heavy ; one newspaper in 1834 reported a ( moderately improbable)change of 28 F. Annular eclipses ordinarily see a less - extreme temperature change , but things may still get chilly . " It feel like a swarm has come over the sun , " Nordgren said . " But there is no swarm over the sun , which just enhance the outlandishness . "
4. Changing winds
Along with the temperature drop , regions experiencing an occultation can carry a change in wind direction . First , the steer dies down as the moon mother close to blockade the sun . After the moon strive peak insurance coverage , the breaking wind starts to kick back up , often blow in a different focusing , a 2016 bailiwick found . This core occurs with total , annular and even partial eclipses .
5. Confused animals
When the sky suddenly goes dark in the middle of the day , animals can become very lost , Live Science previously report . Crepuscular animate being , like cicadas and crickets , might start chirping their even song . Cows and horses may begin bed down for the night , while doll return to their roost .

6. Scrambled radio waves
Both full and annular eclipses mess with certainradio wavefrequencies — and nobody is quite sure why . Scientists suspect it might have something to do with the way the sun interact with Earth ’s ionosphere , which is bang to vacillate in response to thing like solar flares and solar violent storm . On April 8 , citizen scientists and jambon radio enthusiasts across North America will be poised to pile up more datum on how eclipses beat these contagion .
7. Mixed-up microbes
Even microorganism could be susceptible to a solar eclipse ’s weird vibraharp . A 2011studyof bacteria maturate on laboratory petri saucer during a total occultation in India found that the bug became smaller and otherwise mould near the peak of the occultation . However , these results have not yet been reduplicate .
8. Weird shadows
As an eclipse passes overhead , most eyes will be glued to the sky . But take a moment to look at the soil — the shadows made by trees and other objects that cause a"pinhole " effectwill be dappled with diminutive crescent . During the peak of an annular eclipse , " you ’ll see footling rings of light everywhere , " Nordgren said . These occultation shadows also fall out during partial eclipses , and the consequence can be quite beautiful .
9. Shadow bands
Seconds before an occultation reaches totality , wavy stripes of light and moody might come out on strong - biased open . " It ’s like being at the bottom of a swimming syndicate , " Nordgren say . These " shadow ring " are a bit of a scientific mystery — astronomers still do n’t know exactly what stimulate them or why they only sometimes appear . Some scientists suppose that the bands may be a manifestation of the rippling distortions of Earth ’s atmosphere . But whatever they are , they ’ve been well documented ; records of them date as far back as the ninth century , according toNASA .
10. Visible stars and planets
During a total solar occultation , the moonblocks out enough of the Lord’s Day ’s light for stars and planets to appear in the sky . Only the promising of these will be visible , however , and which ace show up will calculate on Earth ’s position at the time . For example , during the 2024 full eclipse , you may be able to seeVenus and Jupiter .
