A partial eclipse of the Sun occurred on Sunday 13 September, 2015 UT, lasting from 04:41–09:06 UT. A moderate partial eclipse, with 79% of the Sun covered for viewers closest to the center, created an interesting spectacle for observers from southern Africa and parts of Antarctica.

The timings of the phases of the overall eclipse worldwide are as follows. In any particular place it would have been seen for a significantly shorter duration as the shadow moved across the Earth:

Partial eclipse began: 04:41:40 UT
Maximum eclipse: 06:54:11 UT
Partial eclipse ended: 09:06:25 UT

During this eclipse the Sun was 0.530° in apparent diameter, 0.6% smaller than average. The Moon was just a day before apogee, making it extremely small. At maximum eclipse it was 0.490° in apparent diameter, which is 7.7% 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.

Visibility

The eclipse will be visible from southern Angola, Zambia, Malawi, and Mozambique south, as well as the southern half of Madagascar. The eclipse will be quite small and hard to see, though, except in the far south of Africa.

In most of Namibia and western South Africa, the eclipse will begin before the Sun rises; however, the moment of maximum eclipse will be occur after sunrise.

The following table summarises the circumstances at various places; "Coverage" is the percentage of the Sun's diameter which will be covered at maximum eclipse:

Place Start Maximum Coverage End
Namibe sunrise 05:16 UT 1% 05:27 UT
Namacunde sunrise 05:19 UT 7% 05:45 UT
Windhoek sunrise 05:25 UT 19% 06:11 UT
Cape Town sunrise 05:43 UT 42% 06:50 UT
Gaborone 04:43 UT 05:32 UT 23% 06:26 UT
Port Elizabeth 04:45 UT 05:47 UT 42% 06:57 UT

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.
