An annular eclipse of the Sun occurred on Tuesday 10 January, 1815 UT (29 Dec, 1814 Old Style), with maximum eclipse at 13:56 UT. A small annular eclipse covered only 91% of the Sun in a very broad path, 438 km wide at maximum, and lasted 7 minutes and 55 seconds.

The annular eclipse lasted for 7 minutes and 55 seconds. Maximum eclipse was at 13:56:54 UT.

During this eclipse the Sun was 0.542° in apparent diameter, 1.7% larger than average. The Moon was just a day before apogee, making it very small. At maximum eclipse it was 0.496° in apparent diameter, which is 6.7% 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.

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.
