Ever wondered why you shouldn't look at an eclipse?

"We already have free glasses". For the August 21 eclipse, the longest period when the moon obscures the sun's entire surface along its path will last about two minutes and 40 seconds, according to NASA.

Wisconsinites who are not traveling to get a look at the total eclipse of the sun by the moon that will occur along a 70-mile-wide swath stretching from OR to SC will see a partial eclipse. The eclipse will last longest near Carbondale, Illinois: two minutes and 44 seconds.

Let's consider how your eyes normally react to the sun. Thankfully, we'd had ample time to prepare-it's not like we didn't know this eclipse was coming. This will happens also thanks to the volunteers joining the project. The country's last total solar eclipse stretching from coast to coast, on June 8, 1918, came in over OR and Washington, and made a beeline for Florida. And it's been almost a century since a total solar eclipse was visible coast to coast.

Unlike a major sports event or a music festival, where lots of people gather in one place and try to use social media at the same time, the eclipse is unique in its scale and spread.

Nasa is teaming up with Google to give solar eclipse glasses to institutions and groups along the path of the totality, where the eclipse will be visible.

Solar eclipses occur when the moon passes between the sun and Earth. For comparison, 6,000 MW is the amount of power needed to run six million homes, or a city the size of Los Angeles.

NY isn't one of the 14 states in the path of totality, the period of total eclipse when the sun is completely blocked by the moon. EIA's capacity and generation data for small-scale solar PV systems is only available at the state level.

Nasa's website says: "Most digital cameras with telephoto lenses of 100 mm or larger will show a disk for the eclipse that will show some detail". Before that, in 1970, a total solar eclipse skirted the Atlantic coastline from Florida to Virginia. The ionosphere is Earth's layer ionized by solar and cosmic radiation and Montogomery's plan is to use the long-distance radio so as to bounce off the ionosphere layer.

Needless to say, California won't be the only state facing these issues.

He also suggests that photographers make sure their tripods are correctly adjusted and that batteries are swapped out just prior to totality.
