An annular solar eclipse occurred at the Moon's ascending node of the orbit on Monday, January 26, 2009. 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. It had a magnitude of 0.9282 and 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.

Occurring only 3.3 days after apogee (January 23, 2009), the Moon's apparent diameter was smaller.

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.
