An annular eclipse of the Sun occurs on Thursday 1 September, 2016 UT, lasting from 06:13–12:00 UT. A large annular eclipse will cover 97% of the Sun, creating a dramatic spectacle for observers in a path up to 100 km wide; it will last 3 minutes and 6 seconds at the point of maximum eclipse. It will be seen across central Africa southwards to Madagascar and into the Indian Ocean. The partial eclipse will be visible across most of Africa and parts of the Middle East.

The timings of the phases of the overall eclipse worldwide are as follows. In any particular place it will be seen for a significantly shorter duration as the shadow moves across the Earth:

Partial eclipse begins: 06:13:08 UT
Annular eclipse begins: 07:17:50 UT
Maximum eclipse: 09:06:54 UT
Annular eclipse ends: 10:55:54 UT
Partial eclipse ends: 12:00:40 UT

During this eclipse the Sun will be 0.528° in apparent diameter, 0.9% smaller than average. The Moon will be 10 days after perigee and 5 days before apogee. At maximum eclipse it will be 0.514° in apparent diameter, which is 3.1% 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.

West Africa

The eclipse arrives in Gabon at 07:39 UT, at which point the annular phase will last 2 minutes 52 seconds, and will be visible over a path 124 km (77.1 miles) wide. The eclipse then moves off over Congo and the Dem. Rep. of Congo, arriving in Tanzania at 08:35 UT over Lake Tanganyika; by this time the duration of the annular phase will be up to 3 minutes and 4 seconds.

East Africa

The eclipse path crosses south-east over Tanzania, where the maximum eclipse of 3 minutes and 6 seconds will occur at 09:06 UT. It then crosses into Mozambique, arriving there at 09:11 UT, and into the sea at 09:19 UT.

Madagascar, Mascarene Islands

The annular eclipse arrives at Madagascar at 09:39 UT, where the duration of the annular phase will still be over 3 minutes, and the annular eclipse will be visible over a path 101 km (62.8 miles) wide. It crosses Madagascar south-east, reaching the sea again at 09:51 UT.

Finally, most of Réunion will see the annular eclipse at about 10:09 UT. Although the island is not on the centreline, the duration in the south-west should be quite good, as the centreline duration is still over 3 minutes.

Interactive Map

This map shows the visibility of the eclipse. The shaded area will see the annular solar eclipse; however, near the edges of this area, the eclipse will be very short. The bold line shows the centre of the path, where the eclipse will last longest, so this is where you want to be if possible.

Use the zoom controls to zoom in and out; hover your mouse over any point on the centreline to see the time and duration of the eclipse at that point. You can pan and zoom the map to see detail for any part of the eclipse path.

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.
