A partial eclipse of the Sun occurred on Friday 1 July, 2011 UT, lasting from 07:53–09:22 UT. With only 10% of the Sun covered at maximum eclipse, this was a very marginal eclipse at best, and rather uninteresting. It was visible from a small patch of ocean near Antarctica.

The timings of the phases of the overall eclipse worldwide are as follows. In any particular place it would have been seen for a significantly shorter duration as the shadow moved across the Earth:

Partial eclipse began: 07:53:47 UT
Maximum eclipse: 08:38:24 UT
Partial eclipse ended: 09:22:45 UT

During this eclipse the Sun was 0.524° in apparent diameter, 1.6% smaller than average. The Moon was 7 days after apogee and 6 days before perigee. At maximum eclipse it was 0.521° in apparent diameter, which is 1.8% smaller than average. This has no real effect on this eclipse, since the Moon's central shadow misses the Earth, making this a partial eclipse. The statistics page has information on the ranges of the sizes of the Sun and Moon.

This tiny partial eclipse must surely set a record for the most insignificant solar 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.
