4 Apr, 1949 BC
max: 15:04 UT
Penumbral Lunar Eclipse
(penum. mag. 0.11; Saros 20)
In this extremely marginal eclipse, the Moon barely clipped the edge of the Earth's penumbral shadow. This caused a microscopic darkening of just 11% of the Moon's disc for 1 hour and 41 minutes, which was essentially impossible to see.
   
15 Apr, 1931 BC
max: 21:34 UT
Penumbral Lunar Eclipse
(penum. mag. 0.25; Saros 20)
This very subtle penumbral eclipse was essentially invisible to the naked eye; though it lasted 2 hours and 33 minutes, just 25% of the Moon's disc was in partial shadow (with no part of it in complete shadow).
   
26 Apr, 1913 BC
max: 04:00 UT
Penumbral Lunar Eclipse
(penum. mag. 0.40; Saros 20)
This very subtle penumbral eclipse was essentially invisible to the naked eye; though it lasted 3 hours and 11 minutes, just 40% of the Moon's disc was in partial shadow (with no part of it in complete shadow).
   
7 May, 1895 BC
max: 10:23 UT
Penumbral Lunar Eclipse
(penum. mag. 0.56; Saros 20)

17 May, 1877 BC
max: 16:45 UT
Penumbral Lunar Eclipse
(penum. mag. 0.72; Saros 20)
This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 72% of the Moon's disc was partially shaded by the Earth (none of it was in total shadow), which caused a gentle shadow gradient across its disc at maximum; the eclipse as a whole lasted 4 hours and 7 minutes.

max: 23:09 UT
Penumbral Lunar Eclipse

Penumbral Lunar Eclipse
(penum. mag. 0.10; Saros 20)
In this extremely marginal eclipse, the Moon barely clipped the edge of the Earth's penumbral shadow. This caused a microscopic darkening of just 10% of the Moon's disc for 1 hour and 24 minutes, which was essentially impossible to see.
