Solar eclipse of May 10, 2013


An annular solar eclipse occurred at the Moon's descending node of orbit between Thursday, May 9 and Friday, May 10, 2013, with a magnitude of 0.9544. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus. An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring about 3.6 days before apogee, the Moon's apparent diameter was smaller.
Annularity was visible from parts of Western Australia, Northern Territory and Queensland, Australia, the Louisiade Archipelago, the Solomon Islands, and Kiribati. All land within the path of annularity was west of the 180th meridian, except Tabuaeran in Kiribati. However, time zone of the Line Islands including Tabuaeran was changed from UTC−10 to UTC+14 in 1995, so annular eclipse visible from land was completely on May 10.
A partial eclipse was visible for parts of Indonesia, Australia, New Zealand, Oceania, and Hawaii. Part of these areas are west of the 180th meridian, seeing the eclipse on May 10, and the rest east of the 180th meridian, seeing the eclipse on May 9.

Visibility

Annularity was visible from a 171 to 225 kilometre-wide track that traversed Australia, eastern Papua New Guinea, the Solomon Islands, and the Gilbert Islands, with the maximum of 6 minutes 3 seconds visible from the Pacific Ocean east of French Polynesia.

Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight. The first and last eclipse in this sequence is separated by one synodic month.
