A total eclipse of the Moon occurs on Saturday 21 August, 2184 UT, with maximum eclipse at 22:31 UT. A shallow total eclipse will see the Moon in relative darkness for 54 minutes and 48 seconds. The Moon will be 14% of its diameter into the Earth's umbral shadow, and should be significantly darkened. The partial eclipse will last for 3 hours and 21 minutes in total.
The penumbral eclipse lasts for 5 hours and 22 minutes.
The partial eclipse lasts for 3 hours and 21 minutes.
The total eclipse lasts for 54 minutes and 48 seconds.
Maximum eclipse is at 22:31:50 UT.
During this eclipse the Moon will be just 3 days before perigee, making it relatively large.
At maximum eclipse it will be 0.546° in apparent
diameter, which is 2.8% larger than average.
The statistics page has information on the ranges of the sizes of
the Sun and Moon, and the Moon data page displays detailed
information on the Moon's key dates.
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.

The primary source of all the information on eclipses presented here at Hermit Eclipse. (NASA Goddard Space flight Center)
are in the TDT timescale.
The Sun and Moon distances are shown in km, and as a
percentage of their minimum - maximum distances; hence 0%
is the closest possible (Earth's perihelion, or the
Moon's closest possible perigee) and 100% is
the farthest (aphelion, the farthest apogee).
