Template:Short description Script error: No such module "Unsubst". Script error: No such module "Solar eclipse". An annular solar eclipse occurred at the Moon's ascending node of orbit on Monday, January 26, 2009,[1][2][3] with a magnitude of 0.9282. 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 3.3 days after apogee (on January 23, 2009, at 0:10 UTC), the Moon's apparent diameter was smaller.[4]

The eclipse was visible from a narrow corridor beginning in the south Atlantic Ocean and sweeping eastward 900 km south of Africa, slowly curving northeast through the Indian Ocean. Its first landfall was in the Cocos Islands followed by southern Sumatra and western Java. It continued somewhat more easterly across central Borneo, across the northwestern edge of Celebes, then ending just before Mindanao, Philippines. The duration of annularity at greatest eclipse lasted 7 minutes, 53.58 seconds, but at greatest duration lasted 7 minutes, 56.05 seconds. A partial eclipse was visible for parts of Southern Africa, East Antarctica, Southeast Asia, the Philippines, and Australia.

The date of this eclipse was the exact day of Lunar New Year, celebrated in parts of Asia, where this eclipse was visible.

Eclipse season

Script error: No such module "Labelled list hatnote". This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) 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.

Solar eclipses of 2008–2011

This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[6]

The partial solar eclipses on June 1, 2011 and November 25, 2011 occur in the next lunar year eclipse set.

Saros 131

This eclipse is a part of Saros series 131, repeating every 18 years, 11 days, and containing 70 events. The series started with a partial solar eclipse on August 1, 1125. It contains total eclipses from March 27, 1522 through May 30, 1612; hybrid eclipses from June 10, 1630 through July 24, 1702; and annular eclipses from August 4, 1720 through June 18, 2243. The series ends at member 70 as a partial eclipse on September 2, 2369. Its eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.

The longest duration of totality was produced by member 28 at 58 seconds on May 30, 1612, and the longest duration of annularity was produced by member 50 at 7 minutes, 54 seconds on January 26, 2009. All eclipses in this series occur at the Moon’s ascending node of orbit.[7]

Series members 39–60 occur between 1801 and 2200:

Metonic series

The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's ascending node.
