A partial eclipse of the Moon occurs on Tuesday 21 May, 2999 UT, with maximum eclipse at 12:07 UT. The Moon will be almost covered by the Earth's shadow in a very deep partial eclipse, lasting 3 hours and 24 minutes. With 91% of the Moon in shadow at maximum eclipse, this will be quite a memorable event.
The penumbral eclipse lasts for 5 hours and 57 minutes.
The partial eclipse lasts for 3 hours and 24 minutes.
Maximum eclipse is at 12:07:36 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.
