An annular eclipse of the Sun occurred on Friday 16 May, 1817 UT (4 May, 1817 Old Style), with maximum eclipse at 06:58 UT. The Sun was 95% covered in a moderate annular eclipse, lasting 6 minutes and 30 seconds and covering a broad path up to 194 km wide.

The annular eclipse lasted for 6 minutes and 30 seconds. Maximum eclipse was at 06:58:02 UT.

During this eclipse the Sun was 0.527° in apparent diameter, 1.1% smaller than average. The Moon was just 2 days past apogee, making it very small. At maximum eclipse it was 0.500° in apparent diameter, which is 5.9% 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.

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.
