November 1976 lunar eclipse

A penumbral lunar eclipse took place on Saturday, November 6, 1976, the second of two lunar eclipses in 1976, the first being on May 13. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 83.827% 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, 25 minutes and 52.1 seconds. Occurring only 0.3 days after apogee (Apogee on Saturday, November 6, 1976), the Moon's apparent diameter was 6.5% smaller than average.[1]
