A partial lunar eclipse took place on Saturday, February 21, 1970. It was the first of two partial lunar eclipses in 1970, the other being on August 17 of the same year. A tiny bite out of the Moon may have been visible at maximum, though just 5% of the Moon was shadowed in a partial eclipse which lasted for 52 minutes and 42 seconds. A shading across the moon from the Earth's penumbral shadow should have been visible at maximum eclipse.
