An annular solar eclipse occurred at the Moon's descending node of orbit on Sunday, February 26, 2017, with a magnitude of 0.9922. 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 4.9 days before perigee (on March 3, 2017, at 13:30 UTC), the Moon's apparent diameter was larger.
The eclipse was visible across southern Chile and Argentina in the morning and ended in Angola and southwestern Katanga, Democratic Republic of the Congo at sunset. In Argentina, the best places to see the eclipse were located in the south of the Chubut Province, in the towns of Facundo, Sarmiento and Camarones. A partial eclipse was visible for parts of southern South America, southern and western Africa, and 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.
