August 1969 lunar eclipse
A penumbral lunar eclipse took place on Wednesday, August 27, 1969, the second of three penumbral lunar eclipses in 1969, the first being on Wednesday, April 2, and the last being on Thursday, September 25. In this extremely marginal eclipse, the Moon barely clipped the edge of the Earth's penumbral shadow. This caused a microscopic darkening of just 1.337% of the Moon's disc for 31 minutes and 32.4 seconds, which was essentially impossible to see. Occurring only 1.8 days after perigee (Perigee on Monday, August 25, 1969), the Moon's apparent diameter was 4.3% larger than average.[1] This is the last lunar eclipse of Saros 108.
