Keep your eyes safe while viewing eclipse

'Alarming reports' of unsafe eclipse glasses sold online have officials warning public

"We want to see if animals are having a reaction at the 90 percent, 80 percent or even 75 percent mark", said Ricard, who is helping spearhead the project. It will appear as an upward-pointing arc, like the top of a fingernail.

During a total eclipse, observers can see the solar corona, a superheated plasma 2 million degrees in temperature.

In the eclipse's "path of totality", the sun will shrink to a sliver before going completely dark for about two and a half minutes.

Well, if looking at an eclipse is like falling in love, I strongly advise protection.

Blair said the moon will begin to cover the sun around 1:03 p.m.

From ionospheric point of view, the expected effect of solar eclipse is a significant reduction in solar EUV ionization (solar EUV radiation is blocked) and thus in the amount of ionospheric total electron content (TEC) with respect to nominal conditions along the eclipse path.

"The total solar eclipse is an exciting event, which could cause distractions for motorists", Illinois State Police Director Leo Schmitz said. When total eclipse begins in western OR, the partial eclipse will just be starting here in Baltimore. Everyone on the continent will be able to view at least a partial eclipse. Only during totality is it safe to look directly at the eclipse with the naked eye.

Staring at the sun can damage an eye's retina, causing temporary or even permanent damage. People can also view the eclipse with a pinhole projector, a card with a small hole through it, to project an image of the sun.

NASA advises anyone wanting to look directly at the eclipse consult the American Astronomical Society for a list of reputable vendors of "eclipse glasses" and filters. So for those cities - and anywhere else with a partial eclipse - you need to keep those solar specs on the whole time.

On Aug. 21, the entire viewing area will be plunged into darkness. It's fine to wear them as long as you want, provided they're no more than three years old.

In a 70-mile wide band from central OR through SC, a total eclipse of the sun will be visible across the entire continental United States for the first time in nearly 40 years. That eclipse took a somewhat similar path as this month's will, from OR to Florida. Solar eclipse glasses will be provided to participants. The path of totality for the 2024 eclipse will be only about 300 miles from Baltimore at its closest, visible from Texas to Maine. The next solar eclipse in Kansas will be in 2045, according to local officials.

Samantha Blair, assistant professor of physics and astronomy, spoke about what actually does happen during an eclipse.

Seeing the sun required special lens covers. Twice a year, the moon's orbit crosses that sun-Earth plane, which astronomers call the ecliptic, but that doesn't usually coincide with the new moon. You may even forget the eclipse was going to happen that day. The sky becomes very dark, as if it were night. Without that, eclipses wouldn't be almost as dramatic, if possible at all.
