An annular eclipse of the Sun occurred on Friday 8 April, 1921 UT (26 Mar, 1921 Old Style), lasting from 06:51–11:37 UT. A large annular eclipse covered 98% of the Sun, creating a dramatic spectacle for observers in a broad path up to 192 km wide; it lasted 1 minute and 50 seconds at the point of maximum eclipse. It was seen in a broad south-west / north-east band covering the Hebrides and north-west Scotland, and north-western Norway and the Arctic.

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: 06:51:22 UT
Annular eclipse began: 08:21:03 UT
Maximum eclipse: 09:14:38 UT
Annular eclipse ended: 10:07:48 UT
Partial eclipse ended: 11:37:34 UT

During this eclipse the Sun was 0.532° in apparent diameter, around average. The Moon was 6 days after apogee and 8 days before perigee. At maximum eclipse it was 0.519° in apparent diameter, which is 2.2% 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.

This was the last annular eclipse in this series to pass over Britain. The next eclipse in the triple-Saros series happened on May 11, 1975; it was a partial eclipse.

The eclipse centreline just touched Cape Wrath, but the annular eclipse extended to Dingwall. The south-east edge of the path ran from Tobermory to Dingwall, and touched the coast at Wick.

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.

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.
