However, there was an entrepreneur with 2,000 pairs of paper and film solar eclipse glasses for sale Friday afternoon - for $10 a pair. A tripod is a great piece of gear to have as well - it will make sure there isn't any shake from your hand, and you can easily set it up to shoot a time-lapse and not have to think about it, giving you more time to enjoy watching. Has their frequency changed over time?
A solar eclipse occurs when the Moon passes between Earth and the sun, thereby totally or partly obscuring the image of the sun for a viewer on Earth. "This eclipse is a celestial phenomenon and cultural moment that can't be missed, and we couldn't imagine a better partner than Twitter to celebrate this with".
"They don't repeat on a time schedule like the seasons of the year", he adds.
A total solar eclipse can sometimes take as long as 7½ minutes.
In 1776, the same year the USA declared its independence, a total solar eclipse was visible over the US and in no other country, just as the eclipse will be this year.
He has calculated when and where these eclipses will happen around the world up until 2030.
That's the big show, where the Moon completely blocks out the Sun. Buffalo falls north of the totality line, so the Southern Tier can expect about a 75 percent eclipse, the rest of us about 72 percent.
The path of totality - where day briefly becomes night - will pass over OR, continuing through the heartland all the way to Charleston, South Carolina.
The sun will disappear - for a short time - across America on August 21, 2017.More news: Solar Eclipse 2017: Clouds could block New Orleans' view
"It's not every day you get the chance to see a solar eclipse", said Laura Wight, director of eLearning and library services. "By global standards, they are so black when you put them on you can not see any light, through these you look at the sun it's a little orange ball".
Overall, about half the nation is likely to get favorable eclipse viewing weather, said Mike Musher, a meteorologist at the weather service's Weather Prediction Center.
Fred Espenak, also known as "Mr. Eclipse", is a retired NASA scientist.
The moon will be first visible in front of the edge of the sun around 1 p.m.
Library officials said they've been receiving hundreds of calls from the community inquiring about the glasses.
As I make my final preparations for my eclipse travels (rural western Wyoming, if you're curious) I'm hearing stories that are making me very unhappy: Some school districts across the country are telling children to stay inside during the eclipse, out of fear they'll damage their eyes.
"Because the Moon's orbit is tipped about 5 degrees to the Earth's orbit around the Sun", Dr Espenak says. Some NASA officials are predicting that this could be one of the worst traffic days in US history, because so many people nearby the regions of totality will want to drive in to see the full eclipse in all its glory.
