Timezone / Date

You have not selected a timezone for eclipse timings, so all times are shown in UT (essentially GMT).

Accuracy

Due to the erratic rotation of the Earth, the time and location of the eclipse cannot be forecast perfectly. This eclipse's time is estimated to be accurate ± 44m26s (with 95% confidence). This equates to an error in longitude of ± 11 degrees, or around ± 1154 km (717 miles) at the latitude of greatest eclipse.

A penumbral eclipse of the Moon occurs on Tuesday 21 January, 2820 UT, with maximum eclipse at 08:37 UT. In this extremely marginal eclipse, the Moon barely clips the edge of the Earth's penumbral shadow. This will cause a microscopic darkening of just 13% of the Moon's disc for 1 hour and 52 minutes, which will be essentially impossible to see.

The penumbral eclipse lasts for 1 hour and 52 minutes. Maximum eclipse is at 08:37:59 UT.

Interactive Map

This map shows the visibility of the eclipse at maximum eclipse, when it will be visible within the bright area on the map. Note that the map is approximate, and if you are near the edge of the area of visibility, the moon will be very close to the horizon and may not be practically visible.

You can use the zoom controls to zoom in and out, and pan to see areas of interest. The green marker in the centre shows where the Moon will be directly overhead at maximum eclipse.

The interactive map is currently not available.
