Expedition measures solar motions seen during last summer’s total solar eclipse

“During the August 21, 2017, solar eclipse, our dozens of telescopes and electronic cameras collected data during the rare two minutes at which we could see and study the sun’s outer atmosphere, the corona,” reported solar-astronomer Jay Pasachoff to the American Astronomical Society, meeting in Denver during June 4-7. Pasachoff, Field Memorial Professor of Astronomy at Williams College, discussed results from his team’s observations made in Salem, Oregon, and measurements that his team has made of extremely rapid motions in the corona.
