An annular eclipse of the Sun occurred on Thursday 10 June, 2021 UT, lasting from 08:12–13:11 UT. The Sun was 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 was visible in northern Canada, the arctic, and far north-eastern Russia. The partial eclipse was 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 would have been seen for a significantly shorter duration as the shadow moved across the Earth:

Partial eclipse began: 08:12:15 UT
Annular eclipse began: 09:49:43 UT
Maximum eclipse: 10:41:51 UT
Annular eclipse ended: 11:33:45 UT
Partial eclipse ended: 13:11:16 UT

During this eclipse the Sun was 0.525° in apparent diameter, 1.5% smaller than average. The Moon was just 2 days past apogee, making it very small. At maximum eclipse it was 0.495° in apparent diameter, which is 6.7% smaller than average; this was not large enough to cover the Sun, which is why this was 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 saw the annular solar eclipse; however, near the edges of this area, the eclipse was very short. The bold line shows the centre of the path, where the eclipse lasted longest.

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.

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 listingsGSFC Eclipse Web Site

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, and the Moon data page displays detailed information on the Moon's key dates.
