A total eclipse of the Sun occurred on 17 April, 1520 UT Old Style, with maximum eclipse at 13:33 UT. A dramatic total eclipse plunged the Sun into darkness for 5 minutes and 15 seconds at maximum, creating an amazing spectacle for observers in a broad path up to 226 km wide.

The total eclipse lasted for 5 minutes and 15 seconds. Maximum eclipse was at 13:33:50 UT.

During this eclipse the Sun was 0.528° in apparent diameter, 0.8% smaller than average. The Moon was just a day past perigee, making it very large. At the start and end of the eclipse the Moon was 0.552°, and at maximum eclipse 0.561°, which is 5.6% larger than average; hence it covered the Sun, making this a total eclipse. The statistics page has information on the ranges of the sizes of the Sun and Moon.

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 listings 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.
