An uncommon incident in orbit could cause some weird events here on Earth as the North American solar eclipse on April 8, 2024, is anticipated to reach totality in 15 US states.
What can Americans expect to happen in the skies and on the ground?
FoxNews reports eight strange things that may happen during a solar eclipse.
Baily’s beads
Baily’s beads are a peculiar effect that happens when the moon approaches the sun during a solar eclipse.
The Diamond Ring Effect is a sliver of light at the edge of an eclipse that can be safely viewed with correct eyewear.
This “interesting edge effect,” according to Johns Hopkins University astrophysicist Dr. Bill Blair, may be visible just as the moon covers or begins to reveal the sun.
Based on “the phenomenon known as ‘Baily’s beads’ … the sun can actually peak through lunar valleys right along the edge of the moon’s limb,” that’s what he claimed.
Blair noted that eclipse viewers can maximise their chances of viewing effects like these by travelling along the “edge” of the total eclipse zone. Blair
Animal behaviour
During a solar eclipse, wildlife species have reacted as if day suddenly turned to night.
During an eclipse, local animals and birds often “prepare for sleep or behave confusedly,” according to the University of Dallas.
Both physical and auditory animal behaviours will shift during the eclipse, National Geographic noted in an article.
“The early onset of darkness disrupts animals’ circadian rhythms, sparking a possible chorus of owl hoots, cricket chirps or even coyote calls, depending on the eclipse-viewing location,” NatGeo wrote.
Because of this expected shift in sound, NASA has released its Eclipse Soundscapes Project, prompting eclipse viewers to pay attention and record differences in animal behaviours in their area.
“Reports of these atypical animal behaviours date back centuries, but the effects of an eclipse on plant and animal life are not fully understood,” NASA wrote in an article.
“The NASA-funded Eclipse Soundscapes Project will collect the sights and sounds of a total solar eclipse with help from interested members of the public to better understand how an eclipse affects different ecosystems.”
Strange shadows
The changing position of the sun’s light can create some interesting shadows on Earth.
Blair said that as the eclipse’s totality approaches, light filtered through tree leaves casts crescent-shaped shadows.
NASA also recommends using a pinhole projector to examine photographs of the crescent sun.
According to Blair, these pinhole cameras can also be used during the partial phases of the eclipse to replace protective eyewear.
“Even more impressive, if you have a colander or a big soup spoon with small holes in it, hold it up, and you will get a whole bunch of little eclipses,” he added.
Only during total eclipses can unusual shadow bands be visible seconds before totality.
NASA disclosed that shadow bands can appear on plain-coloured surfaces as thin, undulating lines of alternating light and dark.
The effect resembles the gloss of a swimming pool.
Colder weather
The weather during a solar eclipse could change rather quickly.
Local temperatures could drop more than 20 degrees near eclipse totality, the University of Dallas said.
This is because when sunlight fades, the weather starts to cool down.
NASA reported that a 2001 eclipse in Zambia dropped the air temperature by nearly 15 degrees.
Windy conditions
In addition to temperature fluctuations, a solar eclipse may bring windy conditions.
According to a 2016 study from the University of Reading, eclipses can take up wind speeds and modify wind directions.
“As the sun disappears behind the moon, the ground suddenly cools, just like at sunset,” University of Reading professor Giles Harrison stated in a press release.
“This means warm air stops rising from the ground, causing a drop in wind speed and a shift in its direction, as the slowing of the air by the Earth’s surface changes.”
Radio interference
Eclipses are known to disrupt radio frequencies.
This is due to a “sudden reduction in solar radiation reaching Earth’s atmosphere,” according to NASA.
“Since the ionosphere contains charged particles (ions and electrons) and is responsible for reflecting and refracting radio waves, changes to the ionosphere can also affect radio communications and navigation systems,” according to a NASA press release.
According to NASA, this change in the ionosphere can affect how radio waves “propagate through it,” resulting in signal fading, absorption, and refraction.
Solar prominences
Solar prominences are rare, but they may arise during a solar eclipse.
Onlookers wearing adequate safety glasses may be able to see the solar corona peeping out from beneath the moon’s shadow.
According to NASA, the appearance will appear to be flower petals framing the moon, but the prominence is an extension of the sun’s surface in a red, burning plasma loop.
These prominences extend hundreds of millions of miles into space; scientists are still investigating how and why they form.
Appearance of other planets
Other stars and planets may be visible because the moon would cast a shadow on the sunlight.
The Planetary Society stated that Venus may appear bright to the sun’s right or bottom right.
Jupiter, which may look dimmer, may be seen to the left or higher left of the sun.
What emerges will be determined by weather conditions in each place, but the brightest astronomical features will have the best chance of appearing, according to Live Science.
