Make sure you have the right equipment to view and protect your eyes for this historic event taking place August 21.
Here in Pennsylvania, at its height, the moon will cover between 78 and 80 percent of the moon, beginning with first contact - when the moon seemingly touches the sun - around 1:21 p.m. "You may notice some effects with darkening". Some think that because the sun will be covered it's okay to look at it. The eclipse will end at 11:39 a.m. when everything should be back to normal.
Moorthy cautions anyone watching the eclipse to protect their eyes and never stare directly at the sun. The AAS Solar Eclipse Task Force has been working diligently to compile a list of such vendors, now posted on its Reputable Vendors of Solar Filters & Viewers page.
One of the best ways to view the eclipse is to simply take a piece of paper - heavier paper like construction paper is best - and poke a hole in it with a paperclip.
"We used to say that you should look for evidence that they comply with the ISO 12312-2 global safety standard for filters for direct viewing of the Sun", the organization posted on its website. The glasses allow you to view the sun's natural orange color.
"A partial solar eclipse is interesting; a total solar eclipse is breathtaking", astronomy Professor Bhasker Moorthy said. This will be the first coast-to-coast eclipse in the U.S.in 99 years. "This one is being called the Great North American eclipse because it can be seen from OR to SC".
The eclipse's path of totality will span 70 miles wide. It then headed northeastward up into Canada. The company started planning for this eclipse about two years ago and hired around 60 additional workers. Although we have eclipses from time to time, this one is going to be pretty stellar, to say the least: Possibly the coolest solar event of your lifetime. Odds of seeing it will be much higher east of the Cascades and in the mountains.
Did you know that a total solar eclipse will be visible in parts of the United States on Monday, August 21st, 2017?
