A penumbral lunar eclipse took place on Thursday, November 8, 1984, the last of three lunar eclipses in 1984. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 90% 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 4 hours and 28 minutes.[1]
