Then you can convert that time into decimal hours using an online calculator.

You can figure out how long in minutes it took the moonРІР‚в„ўs shadow to pass over you by taking the difference between these times.

Record the time when totality ended and everything became light again.

Record the time when the totality began and everything was plunged into darkness.

Try This: Because the Earth is a sphere that rotates on its axis, the speed of the moonРІР‚в„ўs shadow during the total solar eclipse varies in different locations.Р”Р„ccording to NASA, the steps to take to roughly calculate how fast the moonРІР‚в„ўs shadow is moving by you are: How fast does the moonРІР‚в„ўs shadow race across America during a total solar eclipse? If youРІР‚в„ўre watching totality from a location where you can see a lot of land features, you may be able to figure that out. It will essentially extend totality from being about two and a half minutes to about 90 minutes. But because this eclipse is going across the United States, it presents an opportunity for people along the line of the eclipse to contribute their images during totality to the Eclipse Megamovie app.

Usually during eclipses scientists only get a few minutes to study the corona before it disappears.

The corona is only visible from Earth during a total solar eclipse when it leaks out from behind the moon and creates a ring of faint streamers around it. Their goal is to get a long look at the sunРІР‚в„ўs mysterious corona, which is its white and wispy outermost layer. Give Back: The Eclipse Megamovie is a wide-scale citizen science project that aims to gather images of the coming eclipse from across the country and stitch them together to provide a continuous view of the event as it travels from the West Coast to the East Coast.

YouРІР‚в„ўll probably be taking pictures during the eclipse, so why not contribute some of those images to science in addition to your Instagram feed?
