A partial lunar eclipse took place on Friday, July 17, 1981, the second of two lunar eclipses in 1981. The Earth's shadow on the Moon was clearly visible in this eclipse, with 55% of the Moon in shadow; the partial eclipse lasted for 2 hours and 43 minutes.[1]
The partial phase of this lunar eclipse was visible in southeastern North America, South America, western Africa, seen rising over northern North America, and setting over Western Europe and Eastern Africa.
It was part of Saros series 119.
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 total solar eclipses of Solar Saros 126.
