A total lunar eclipse took place on Friday, November 29, 1974, the second of two lunar eclipses in 1974. The Moon was plunged into darkness for 1 hour, 15 minutes and 45 seconds, in a deep total eclipse which saw the Moon 28.961% of its diameter inside the Earth's umbral shadow. The visual effect of this depends on the state of the Earth's atmosphere, but the Moon may have been stained a deep red colour. The partial eclipse lasted for 3 hours, 28 minutes and 58.7 seconds in total. The penumbral eclipse lasted for 5 hours, 33 minutes and 11.6 seconds. The partial eclipse lasted for 3 hours, 28 minutes and 58.7 seconds. The total eclipse lasted for 1 hour, 15 minutes and 45 seconds. Occurring only 3.6 days before perigee (Perigee on Tuesday, December 3, 1974), the Moon's apparent diameter was 1.4% larger than average.
