A penumbral eclipse of the Moon occurred on Thursday 21 July, 1785 UT (10 Jul, 1785 Old Style), with maximum eclipse at 23:45 UT. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 71% 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 3 hours and 38 minutes.
The penumbral eclipse lasted for 3 hours and 38 minutes.
Maximum eclipse was at 23:45:29 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.
