The eclipse is expected to cross from Oregon, entering the U.S. at 10:15 a.m. Pacific Daylight Time, and leaving U.S. shores from South Carolina at 2:50 p.m. Eastern Daylight Time, over the course of an hour and a half.
Becoming a citizen scientist through The Global Learning and Observations to Benefit the Environment program begins with downloading NASA's free GLOBE Observer Eclipse APP, which will fuel a nationwide science experiment.
Fourteen states will experience night-like darkness for approximately two minutes in the middle of the day, according to NASA.
"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 scientist project," said Kristen Weaver, deputy coordinator for the project. "We want to inspire a million eclipse viewers to become eclipse scientists."
