A penumbral eclipse of the Moon occurred on 16 September, 1521 UT Old Style, with maximum eclipse at 13:38 UT. This subtle penumbral eclipse eclipse may have been visible to a skilled observer at maximum eclipse. 82% of the Moon's disc was partially shaded by the Earth (none of it was in total shadow), which caused a gentle shadow gradient across its disc at maximum; the eclipse as a whole lasted 3 hours and 52 minutes.

The penumbral eclipse lasted for 3 hours and 52 minutes. Maximum eclipse was at 13:38:19 UT.

During this eclipse the Moon was just 2 days before perigee, making it fairly large. At maximum eclipse it was 0.550° in apparent diameter, which is 3.5% 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.
