A partial eclipse of the Moon occurred on Sunday 22 July, 1804 UT (10 Jul, 1804 Old Style), with maximum eclipse at 17:37 UT. The Moon was almost covered by the Earth's shadow in a very deep partial eclipse, which lasted 3 hours and 16 minutes. With 90% of the Moon in shadow at maximum eclipse, this was quite a memorable event.

The penumbral eclipse lasted for 5 hours and 35 minutes. The partial eclipse lasted for 3 hours and 16 minutes. Maximum eclipse was at 17:37:48 UT.

During this eclipse the Moon was 6 days after apogee and 9 days before perigee. At maximum eclipse it was 0.519° in apparent diameter, which is 2.3% smaller than average. 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 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, and the Moon data page displays detailed information on the Moon's key dates.
