Saros 128 (58 of 73)
Catalog # (SE5000) 9535

An annular solar eclipse took place on May 20, 2012 (May 21, 2012 in local time in the Eastern Hemisphere), with a magnitude of 0.9439. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide.

It was the first annular eclipse in the continental U.S. since the solar eclipse of May 10, 1994 which was also the previous eclipse of this series Solar Saros 128.
