Template:Short description Script error: No such module "Unsubst". Script error: No such module "Solar eclipse". An annular solar eclipse occurred at the Moon’s ascending node of orbit on Thursday, June 10, 2021,[1][2][3][4] with a magnitude of 0.9435. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring 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 2.3 days after apogee (on June 8, 2021, at 3:30 UTC), the Moon's apparent diameter was smaller.[5]

The annular eclipse was visible from parts of northeastern Canada (particularly Ontario and Nunavut), Greenland, the Arctic Ocean (passing over the North Pole),[6] and the Russian Far East. A partial eclipse was visible for parts of northern North America, Europe, and North Asia.[7]

Path

The annular eclipse started at 09:55 UTC for 3 minutes 37 seconds along the northern shore of Lake Superior in Ontario, Canada. The path of the antumbral shadow then headed across Hudson Bay through northwestern Quebec and the Hudson Strait to Baffin Island in Nunavut, where the town of Iqaluit saw 3 minutes and 5 seconds of annularity. After this, it then travelled across Baffin Bay and along the northwestern coast of Greenland, where the point of greatest eclipse occurred at 10:41 UTC in Nares Strait for 3 minutes 51 seconds. The shadow then crossed Ellesmere Island and the Arctic Ocean, passing over the North Pole (which was located away from the central line of the eclipse but saw 2 minutes and 36 seconds of annularity), before heading south towards northeastern Siberia, where the city of Srednekolymsk saw 3 minutes and 35 seconds of annularity at 11:27 UTC. Shortly afterwards, the central line of the annular eclipse ended at 11:29 UTC.[8][9]

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 2018–2021

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.[11]

The partial solar eclipses on February 15, 2018 and August 11, 2018 occur in the previous 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 ascending node.
