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 (ring). 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 (on May 13, 2013, at 14:30 UTC), the Moon's apparent diameter was smaller.
Annularity was visible from parts of Western Australia, Northern Territory and Queensland, Australia, the Louisiade Archipelago (belonging to Papua New Guinea), 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.
