December 1982 lunar eclipse

A total lunar eclipse took place on Thursday, December 30, 1982, the last of three total lunar eclipses in 1982. A shallow total eclipse saw the Moon in relative darkness for 1 hour, 2.8 seconds. The Moon was 18% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours, 15 minutes and 55.2 seconds in total. Occurring only 0.4 days before perigee (Perigee on Thursday, December 30, 1982 at 10:03 p.m. UTC), the Moon's apparent diameter was 6.3% larger than average. The Moon was only 357,154 km (221,925 mi) from the Earth, making it a Super Full Moon.[1] This was a supermoon since perigee was on the same day. It was also a blue moon, the second full moon of December for the eastern hemisphere where the previous full moon was on December 1.[2] Since total lunar eclipses are also known as blood moons, this combination (which would not recur until January 31, 2018[2]) is known as a super blue blood moon.[2]
