Solar eclipse of September 21, 2025
Template:Short description Script error: No such module "Solar eclipse". A partial solar eclipse will occur at the Moon’s descending node of orbit on Sunday, September 21, 2025,[1] with a magnitude of 0.855. A solar eclipse occurs when the Moon passes between the Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.
Partiality will be visible across much of Oceania and Antarctica, with up to 80% coverage being visible at the southernmost point of New Zealand and on Stewart Island on the morning of September 22 local time.[2]

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.

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.
