A penumbral eclipse of the Moon occurred on 20 January, 0577 UT Old Style, with maximum eclipse at 05:22 UT. This very subtle penumbral eclipse was essentially invisible to the naked eye; though it lasted 2 hours and 19 minutes, just 28% of the Moon's disc was in partial shadow (with no part of it in complete shadow).
The penumbral eclipse lasted for 2 hours and 19 minutes.
Maximum eclipse was at 05:22:27 UT.
Interactive Map
This map shows the visibility of the eclipse at maximum eclipse,
when it was visible within the bright area on the map. Note that
the map is approximate, and if you
were near the edge of the area of visibility, the moon was very close
to the horizon and may not have been practically visible.
You can use the zoom controls to zoom in and out, and pan to
see areas of interest. The green marker in the centre shows where
the Moon will be directly overhead at maximum eclipse.
The interactive map is currently not available.
