A total eclipse of the Sun occurs on Saturday 23 September, 2090 UT, lasting from 14:47–19:00 UT. A dramatic total eclipse will plunge the Sun into darkness for 3 minutes and 36 seconds at maximum, creating an amazing spectacle for observers in a very broad path, 463 km wide at maximum. It will be seen in the Arctic, south-west Ireland and England, and north-west France. The partial eclipse will be visible from most of North America, extreme western Europe, and north-west Africa.

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: 14:47:40 UT
Total eclipse begins: 16:10:13 UT
Maximum eclipse: 16:53:50 UT
Total eclipse ends: 17:37:48 UT
Partial eclipse ends: 19:00:15 UT

During this eclipse the Sun will be 0.531° in apparent diameter, 0.3% smaller than average. The Moon will be at perigee, making it very large. At the start and end of the eclipse the Moon will be 0.557°, and at maximum eclipse 0.561°, which is 5.7% larger than average; hence it will cover the Sun, making this a total eclipse. The statistics page has information on the ranges of the sizes of the Sun and Moon.

Greenland

The total eclipse reaches southern Greenland at about 16:35 UT. The path is 433 km (269.1 miles) wide here, and the total eclipse will last 3 minutes 28 seconds on the centreline. After crossing Greenland, the total eclipse reaches the Atlantic at 16:51 UT, just two minutes before maximum eclipse; at this point, the path of totality is 459 km (285.2 miles) wide, and the eclipse will last 3 minutes 35 seconds on the centreline.

Ireland / UK / France

The total eclipse will be visible in south-west Ireland about 17:30 UT. Although the duration on the centreline will be over three minutes at this point, Ireland is just on the fringe of the path of totality, and so will see a much shorter eclipse.

The south-west of England, especially the tip of Cornwall, fares much better, being much closer to the centreline, and should therefore see a longer eclipse, with the maximum around 17:33 UT — the duration on the centreline is still 2 minutes 51 seconds. The broad path of totality covers most of the south coast of England, including all of Cornwall and Devon.

Shortly after this, the eclipse reaches Brittany; then the Channel Islands are lucky enough to be right in the path of the eclipse. Finally, the eclipse finishes in France at 17:37 UT, with parts of Belgium also witnessing a brief total eclipse as the Sun sets. Most of the UK will see the Sun set partially eclipsed.

Interactive Map

This map shows the visibility of the eclipse. The shaded area will see the total 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.
