Ask SAM: What are guidelines for eclipse glasses?

The day the sun disappears

It will be the first lunar eclipse to cross the entirety of the U.S. in 99 years. "Then you will get to totality as you see the corona and as the moon starts to move off, you will get beading again, another partial eclipse and then it will move off". The shadow of the moon will come on shore in OR and pass all the way across the country in about an hour and a half. The moon's shadow usually misses us as it passes by because of the tilt of the earth's axis. He says regular sunglasses block about 60% of light rays while eclipse glasses block 99.9% of light rays.

On Monday, August 21, 2017, all of North America will be treated to an eclipse of the sun.

Because of how the moon orbits the Earth, lunar eclipses always coincide with a full moon, and solar eclipses coincide with the new moon. The last total solar eclipse to even come close to Columbia was in 1442 in Saint Louis - for many, this is a once-in-a-lifetime event.

-The longest period when the moon completely blocks the sun from any given location along the path will be about two minutes and 40 seconds, according to NASA. There will be a "twilight" in the sky during totality. Anyone in that spot will see the sun partially or totally covered up by the moon. There will be a noticed darkening of the sky similar to a cloud blocking the sun. The partial eclipse will end at 12.48 a.m., while the penumbral eclipse will end at 2.20 a.m. on August 8. It's maximum point and the best place to view it will be in Hopkinsville, Kentucky at 1:25 p.m.

The main thing to keep in mind is that you need special glasses to look at the sun.

Ahead of the solar eclipse, here is a guide to getting the right eclipse glasses and solar filters for your camera.

"What you absolutely should not do is search for eclipse glasses on the internet and buy whatever pops up in the ads or search results", the AAS said in a statement.

Astronomers warn people not to use telescopes and to get the solar eclipse protective eyewear. These can and do sometimes break due to the heat buildup on the filter. If you're using a platform like Airbnb, make sure to correspond through the platform. "Those attending will have a chance to see the sun safely with special telescopes created to view the sun in different wavelengths of light".

In Ontario, the Independent Electricity System Operator (IESO) is preparing to have gas plants and the turbines at Niagara Falls make up the difference on eclipse day. The shadows will appear different and take on some pretty cool forms.

Since the moon's orbit is inclined to follow the equator, it means that majority of the instances when the moon eclipses the sun is not actually seen from Earth.
