A total lunar eclipse took place on Friday, April 22, 1921. This was the first total lunar eclipse of Saros cycle 130. A shallow total eclipse saw the Moon in relative darkness for 40 minutes and 6 seconds. The Moon was approximately 7% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours and 22 minutes in total.
A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[1] This lunar eclipse is related to two annular solar eclipses of Solar Saros 137.
