May 1975 lunar eclipse

Total lunar eclipse

A total lunar eclipse took place on Saturday, May 24 and Sunday, May 25, 1975, the first of two total lunar eclipses in 1975. The Moon was plunged into darkness for 1 hour and 28 minutes in a deep total eclipse which saw the Moon 43% of its diameter inside the Earth's umbral shadow. The visual effect of an eclipse 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 and 35 minutes in total. Occurring only 4.4 days after perigee, the Moon's apparent diameter was 0.7% larger than average. The moon was 377,010 km from the Earth at greatest eclipse.
