A penumbral eclipse of the Moon occurred on Monday 31 March, 1828 UT (19 Mar, 1828 Old Style), with maximum eclipse at 10:38 UT. In this extremely marginal eclipse, the Moon barely clipped the edge of the Earth's penumbral shadow. This caused a microscopic darkening of just 19% of the Moon's disc for 2 hours and 7 minutes, which was essentially impossible to see.

The penumbral eclipse lasted for 2 hours and 7 minutes. Maximum eclipse was at 10:38:38 UT.

During this eclipse the Moon was 6 days after apogee and 8 days before perigee. At maximum eclipse it was 0.523° in apparent diameter, which is 1.6% smaller 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.
