A penumbral eclipse of the Moon occurs on Thursday 9 December, 2421 UT, with maximum eclipse at 11:21 UT. This subtle penumbral eclipse may be visible to a skilled observer at maximum eclipse. 69% of the Moon's disc will be partially shaded by the Earth (none of it will be in total shadow), which will cause a gentle shadow gradient across its disc at maximum; the eclipse as a whole will last 3 hours and 50 minutes.
The penumbral eclipse lasts for 3 hours and 50 minutes.
Maximum eclipse is at 11:21:06 UT.
Interactive Map
This map shows the visibility of the eclipse at maximum eclipse,
when it will be visible within the bright area on the map. Note that
the map is approximate, and if you
are near the edge of the area of visibility, the moon will be very close
to the horizon and may not be 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.
