An annular eclipse of the Sun occurs on Tuesday 18 October, 2191 UT, with maximum eclipse at 08:04 UT. The Sun will be 95% covered in a moderate annular eclipse, lasting 3 minutes and 39 seconds and covering a very broad path, 365 km wide at maximum.

The annular eclipse lasts for 3 minutes and 39 seconds. Maximum eclipse is at 08:04:10 UT.

During this eclipse the Sun will be 0.535° in apparent diameter, 0.3% larger than average. The Moon will be 5 days after apogee and 11 days before perigee. At maximum eclipse it will be 0.509° in apparent diameter, which is 4.2% smaller than average; this is not large enough to cover the Sun, which is why this is 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.
