A hybrid eclipse of the Sun occurs on Thursday 20 April, 2023 UT, lasting from 01:34–06:59 UT. The Sun will be darkened for 1 minute and 16 seconds by a dramatic hybrid eclipse covering a narrow path at most 49 km wide. This will be a sight worth seeing, and will be visible in extreme north-western Australia, East Timor, and Indonesia. The partial eclipse will be visible across Australia and southeast Asia.

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: 01:34:16 UT
Central eclipse begins: 02:36:56 UT
Maximum eclipse: 04:16:37 UT
Central eclipse ends: 05:56:35 UT
Partial eclipse ends: 06:59:13 UT

During this eclipse the Sun will be 0.531° in apparent diameter, 0.4% smaller than average. The Moon will be just 4 days past perigee, making it relatively large. At the start and end of the eclipse, the Moon will be 0.530°, which is smaller than the Sun; hence the eclipse will be annular at that point. However, at maximum eclipse the Moon will be 0.538° in apparent diameter, which is 1.3% larger than 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.

Australia

The hybrid eclipse starts as an annular eclipse in the Indian Ocean west of Kerguelen, which will see a partial eclipse covering 92% of the Sun peaking at 02:38 UT. The eclipse path moves north-east, with the central eclipse soon becoming total; it reaches Australia at the North West Cape at 03:28 UT, with total eclipse lasting just over a minute on the centreline. Exmouth will see a total eclipse at 03:30 UT, but lasting only 55 seconds, as it is somewhat north of the centreline.

The eclipse then crosses the Muiron islands and Serrurier Island; the area around Bessieres Island will see both this eclipse and the total eclipse of December 2038. The track reaches Barrow Island at 03:34 UT, at which point the central duration will be up to 1 minute 5 seconds; all of Barrow Island will see a dramatic total eclipse.

East Timor, Indonesia

The eclipse passes over the eastern end of East Timor starting around 04:18 UT; here the total eclipse will last 1 minute 16 seconds on the centreline. Viqueque will see a spectacular total eclipse, as will Lospalos at 04:21 UT. The eclipse leaves East Timor and passes over Kisar at 04:23 UT, then Maopora, Damar Island, and the Watubela archipelago at 04:40 UT. It reaches West Papua at around 04:45 UT, then Biak Island at 04:57 UT. Ater this the eclipse moves off into the Pacific, and terminates over the ocean.

Interactive Map

This map shows the visibility of the eclipse. The area shaded blue will see a total eclipse, and the areas shaded red will see an annular eclipse; however, near the edges of each 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.
