A partial lunar eclipse took place on Monday, April 4, 1977, the first of two lunar eclipses in 1977. Lasting 1 hour and 34.76 minutes, 19.289% of the Moon was in shadow at maximum.[1]
It was completely visible over North America, South America, Europe and Asia, seen rising over the Pacific and setting over the Middle East.
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 partial solar eclipses of Solar Saros 119.
