Penumbral eclipse
Date20 January 1981
Saros cycle114 (57 of 71)
Penumbral263 minutes, 50 seconds

A penumbral lunar eclipse took place on January 20, 1981. In a rare total penumbral eclipse, the entire Moon was partially shaded by the Earth (though none of it was in complete shadow), and the shading across the Moon should have been quite visible at maximum eclipse. The penumbral phase lasted for 4 hours and 24 minutes in all, though for most of it, the eclipse was extremely difficult or impossible to see.[1]

This was a relatively rare total penumbral lunar eclipse with the moon passing entirely within the penumbral shadow without entering the darker umbral shadow.[2]
