An annular eclipse of the Sun occurred on Tuesday 17 September, 1811 UT (5 Sep, 1811 Old Style), with maximum eclipse at 18:43 UT. A small annular eclipse covered only 93% of the Sun in a very broad path, 330 km wide at maximum, and lasted 6 minutes and 51 seconds.

The annular eclipse lasted for 6 minutes and 51 seconds. Maximum eclipse was at 18:43:33 UT.

During this eclipse the Sun was 0.531° in apparent diameter, 0.4% smaller than average. The Moon was just a day past apogee, making it very small. At maximum eclipse it was 0.496° in apparent diameter, which is 6.6% 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.
