An annular eclipse of the Sun occurs on Thursday 10 June, 2021 UT, lasting from 08:12–13:11 UT. The Sun will be 94% covered in a moderate annular eclipse, lasting 3 minutes and 51 seconds and covering a very broad path, 527 km wide at maximum. It will be visible in northern Canada, the arctic, and far north-eastern Russia. The partial eclipse will be visible from Canada, most of Europe, and much of 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: 08:12:15 UT
Annular eclipse begins: 09:49:43 UT
Maximum eclipse: 10:41:51 UT
Annular eclipse ends: 11:33:45 UT
Partial eclipse ends: 13:11:16 UT

During this eclipse the Sun will be 0.525° in apparent diameter, 1.5% smaller than average. The Moon will be just 2 days past apogee, making it very small. At maximum eclipse it will be 0.495° in apparent diameter, which is 6.7% 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.

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.
