Penumbral lunar eclipse August 26, 1980

A penumbral lunar eclipse took place at the Moon's descending node of the orbit on Tuesday, August 26, 1980, the last of three penumbral lunar eclipses in 1980 with a penumbral magnitude of 0.70891. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 70.891% of the Moon's disc was partially shaded by the Earth (none of it was in total shadow), which caused a gentle shadow gradient across its disc at maximum; the eclipse as a whole lasted 3 hours, 34 minutes and 26 seconds.[1]
