An annular eclipse of the Sun occurred on 11 October, 1539 UT Old Style, with maximum eclipse at 23:59 UT. The Sun was 95% covered in a moderate annular eclipse, lasting 5 minutes and 35 seconds and covering a broad path up to 192 km wide.

The annular eclipse lasted for 5 minutes and 35 seconds. Maximum eclipse was at 23:59:07 UT.

During this eclipse the Sun was 0.537° in apparent diameter, 0.7% larger than average. The Moon was just 4 days before apogee, making it fairly small. At maximum eclipse it was 0.509° in apparent diameter, which is 4.1% smaller than average; this was not large enough to cover the Sun, which is why this was an annular 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. For this eclipse, this makes the date shown on this site different to NASA's date.

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.
