An annular eclipse of the Sun occurred on Monday 27 August, 1821 UT (15 Aug, 1821 Old Style), with maximum eclipse at 15:19 UT. The Sun was 97% covered in a moderate annular eclipse, lasting 3 minutes and 38 seconds and covering a path up to 123 km wide.
The annular eclipse lasted for 3 minutes and 38 seconds.
Maximum eclipse was at 15:19:31 UT.
During this eclipse the Sun was 0.528° in apparent
diameter, 0.9% smaller than average. The Moon was just 4 days before apogee, making it relatively small.
At maximum eclipse it was 0.510° in
apparent diameter, which is 3.9% smaller than average; this was not
large enough to cover the Sun, which is why this
was an annular eclipse.
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.

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).
