A hybrid eclipse of the Sun occurs on Sunday 20 September, 2685 UT, with maximum eclipse at 18:10 UT. A fleeting hybrid eclipse will cover a narrow path at most 27 km wide and last for 42 seconds at the point of maximum eclipse.

The hybrid eclipse lasts for 42 seconds. Maximum eclipse is at 18:10:41 UT.

During this eclipse the Sun will be 0.529° in apparent diameter, 0.7% smaller than average. The Moon will be 7 days after apogee and 5 days before perigee. At the start and end of the eclipse, the Moon will be 0.525°, which is smaller than the Sun; hence the eclipse will be annular at that point. However, at maximum eclipse the Moon will be 0.533° in apparent diameter, which is around average, large enough to cover the Sun; and so a total eclipse will be seen at that point. Thus this is a hybrid eclipse. The statistics page has information on the ranges of the sizes of the Sun and Moon.

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 listings 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.
