An annular eclipse of the Sun occurred on Wednesday 4 April, 1810 UT (23 Mar, 1810 Old Style), with maximum eclipse at 01:41 UT. A large annular eclipse covered over 99% of the Sun, creating a dramatic spectacle for observers in a narrow path at most 12 km wide; it lasted just 21 seconds at the point of maximum eclipse.

The annular eclipse lasted for 21 seconds. Maximum eclipse was at 01:41:07 UT.

During this eclipse the Sun was 0.533° in apparent diameter, around average. The Moon was 6 days after perigee and 7 days before apogee. At maximum eclipse it was 0.531° in apparent diameter, which is around 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.

Note that while all dates and times on this site (except where noted) are in UT, which is within a second of civil time, the dates and times shown in NASA's eclipse listingsGSFC Eclipse Web Site

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). The statistics page has information on the ranges of sizes of the Sun and Moon, and the Moon data page displays detailed information on the Moon's key dates.
