A partial lunar eclipse took place on Monday, December 10, 1973, the last of four lunar eclipses in 1973. At maximum eclipse, a small bite out of the Moon should have been visible. The eclipse lasted for 1 hour, 8 minutes and 29.4 seconds, with just 10.069% of the Moon in shadow at maximum.[1] It occurred near perigee, and as described, such event was known as a supermoon.
