July 1980 lunar eclipse

Penumbral lunar eclipse July 27, 1980

A penumbral lunar eclipse took place on Sunday, July 27, 1980, the second of three penumbral lunar eclipses in 1980. This very subtle penumbral eclipse was essentially invisible to the naked eye; though it lasted 2 hours, 17 minutes and 36.3 seconds, just 25.354% of the Moon's disc was in partial shadow. The moon passed in the northern edge of the Earth's penumbral shadow, and was the 70th lunar eclipse of Saros cycle 109.
