A partial eclipse of the Sun occurs on Friday 13 July, 2018 UT, lasting from 01:48–04:13 UT. A small partial eclipse will be visible from a patch of ocean between Australia and Antarctica. With just 34% of the Sun covered for viewers closest to the center, this will be of limited interest.

The timings of the phases of the overall eclipse worldwide are as follows. In any particular place it will be seen for a significantly shorter duration as the shadow moves across the Earth:

Partial eclipse begins: 01:48:17 UT
Maximum eclipse: 03:01:02 UT
Partial eclipse ends: 04:13:43 UT

During this eclipse the Sun will be 0.524° in apparent diameter, 1.6% smaller than average. The Moon will be at perigee, making it very large. At maximum eclipse it will be 0.557° in apparent diameter, which is 4.9% larger 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.

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.
