A partial eclipse of the Sun occurred on Saturday 30 December, 1815 UT (18 Dec, 1815 Old Style), with maximum eclipse at 14:38 UT. A small partial eclipse barely darkened the Sun. With just 43% of the Sun covered for viewers closest to the center, this was of limited interest.

Maximum eclipse was at 14:38:27 UT.

During this eclipse the Sun was 0.542° in apparent diameter, 1.7% larger than average. The Moon was 11 days after perigee and 5 days before apogee. At maximum eclipse it was 0.505° in apparent diameter, which is 4.9% smaller than average. This has no real effect on this eclipse, since the Moon's central shadow misses the Earth, making this a partial 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.
