We would like to invite eclipse viewers around the country to participate in a nationwide science experiment by collecting cloud and air temperature data and reporting it via their phones.

In order to participate, first download the GLOBE Observer app and register to become a citizen scientist. The app will instruct you on how to make the observations. Second, you will need to obtain a thermometer to measure air temperature.

“No matter where you are in North America, whether it’s cloudy, clear or rainy, NASA wants as many people as possible to help with this citizen science project,” said Kristen Weaver, deputy coordinator for the project. “We want to inspire a million eclipse viewers to become eclipse scientists.”

About the eclipse:

On Aug. 21, a total solar eclipse will occur across the entire continental United States. Crossing the country from Oregon to South Carolina over the course of an hour and a half, 14 states will experience night-like darkness for approximately two minutes in the middle of the day. The eclipse enters the U.S. at 10:15 a.m. PDT off the coast of Oregon and leaves U.S. shores at approximately 2:50 p.m. EDT in South Carolina. All of North America will experience at least a partial eclipse. Learn more, here.
