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]
Saros series
[edit]This is the 9th member of Lunar Saros 145. The previous event was the October 1958 lunar eclipse. The next event is the November 1994 lunar eclipse. Solar Saros 152 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.
Eclipse season
[edit]This event followed the Total solar eclipse of October 23, 1976.
Visibility
