A total eclipse of the Moon occurred on 21 May, 1323 UT Old Style, with maximum eclipse at 02:40 UT. A shallow total eclipse saw the Moon in relative darkness for 1 hour and 3 minutes. The Moon was 20% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours and 18 minutes in total.

The penumbral eclipse lasted for 5 hours and 10 minutes. The partial eclipse lasted for 3 hours and 18 minutes. The total eclipse lasted for 1 hour and 3 minutes. Maximum eclipse was at 02:40:47 UT.

During this eclipse the Moon was just a day before perigee, making it extremely large. At maximum eclipse it was 0.564° in apparent diameter, which is 6.1% larger than average. 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 at maximum eclipse, when it was visible within the bright area on the map. Note that the map is approximate, and if you were near the edge of the area of visibility, the moon was very close to the horizon and may not have been 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.

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.
