Solar eclipse of February 26, 2017
Template:Short description Script error: No such module "Solar eclipse". An annular solar eclipse occurred at the Moon's descending node of orbit on Sunday, February 26, 2017,[1][2][3][4] 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.[5]
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
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 2015–2018
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.[7]
The partial solar eclipse on July 13, 2018 occurs in the next lunar year eclipse set.

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 descending node.
