A partial eclipse of the Sun occurred on Thursday 31 August, 1989 UT, with maximum eclipse at 05:30 UT. A moderate partial eclipse, with 63% of the Sun covered for viewers closest to the center, created an interesting spectacle.

Maximum eclipse was at 05:30:50 UT.

During this eclipse the Sun was 0.528° in apparent diameter, 0.9% smaller than average. The Moon was just 4 days before apogee, making it very small. At maximum eclipse it was 0.499° in apparent diameter, which is 6.0% 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.
