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 (Perigee on May 20, 1975), the Moon's apparent diameter was 0.7% larger than average. The moon was 377,010 km (234,263 mi) from the Earth at greatest eclipse.
It was completely visible over North and South America, seen rising over Australia on the evening of Sunday 25 May 1975, and setting over Africa, and Western Europe on the morning of Sunday 25 May 1975.
Lunar saros series 130, repeating every 18 years and 11 days, has a total of 71 lunar eclipse events including 56 umbral lunar eclipses (42 partial lunar eclipses and 14 total lunar eclipses). Solar Saros 137 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[2] This lunar eclipse is related to two annular solar eclipses of Solar Saros 137.
