The eclipse on May 20 was an annular – or ring – eclipse. At its peak, for those standing on the central line of the eclipse, the eclipse resembled a bulls-eye, with a thin ring of the sun visible around the moon.
This eclipse was the first solar eclipse of any kind in the mainland U.S. (not including Hawaii and Alaska) in the 21st century (2001-2100). Plus the May 20, 2012 eclipse was the first time in 18 years that the moon crossed directly in front of the sun as seen from U.S. shores.
