An annular solar eclipse occurred at the Moon's descending node of orbit on Friday, September 22, 2006,[1][2][3] with a magnitude of 0.9352. 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 5 hours after apogee (on September 22, 2006, at 6:20 UTC), the Moon's apparent diameter was smaller.[4]
The path of annularity of this eclipse passed through Guyana, Suriname, French Guiana, the northern tip of Roraima and Amapá of Brazil, and the southern Atlantic. A partial eclipse was visible for parts of South America, West Africa, Southern Africa, the Antarctic Peninsula, and east Antarctica.

Eclipse season
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.
