Timezone / Date

You have not selected a timezone for eclipse timings, so all times are shown in UT (essentially GMT).

Accuracy

Due to the erratic rotation of the Earth, the time and location of the eclipse cannot be forecast perfectly. This eclipse's time is estimated to be accurate ± 0m13s (with 95% confidence). This equates to an error in longitude of ± 0.055 degrees, or around ± 6.1 km (3.7 miles) at the latitude of greatest eclipse.

An annular eclipse of the Sun occurs on Wednesday 21 May, 2031 UT, lasting from 04:13–10:15 UT. The Sun will be 96% covered in a moderate annular eclipse, lasting 5 minutes and 26 seconds and covering a path up to 152 km wide. It will be visible across Angola, Zambia, D.R. Congo, Tanzania, southern India and northern Sri Lanka, the Nicobar islands, Thailand and Malaysia, and Indonesia. The partial eclipse will be visible from much of Africa, the Middle East, south Asia, and western Australia.

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: 04:13:59 UT
Annular eclipse begins: 05:18:29 UT
Maximum eclipse: 07:14:40 UT
Annular eclipse ends: 09:10:56 UT
Partial eclipse ends: 10:15:26 UT

During this eclipse the Sun will be 0.527° in apparent diameter, 1.2% smaller than average. The Moon will be just 4 days before apogee, making it fairly small. At maximum eclipse it will be 0.505° in apparent diameter, which is 4.9% 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.

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.

The interactive map is currently not available.

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.
