An annular solar eclipse will occur at the Moon's descending node of orbit on Saturday, June 1, 2030,[1] with a magnitude of 0.9443. 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 23 hours after apogee (on May 31, 2030, at 7:15 UTC), the Moon's apparent diameter will be smaller.[2]
The annular eclipse will start in northern Africa and will cross the Eurasian continent, including Algeria, Tunisia, Libya, Malta, Greece, northwestern Turkey, southeastern Bulgaria, southeastern Ukraine, Russia, northern Kazakhstan, northeastern China and northern Japan. It will also pass through a number of large cities such as Tripoli, Athens, Istanbul, Krasnodar, Rostov-on-Don, Volgograd, Omsk, Krasnoyarsk and Sapporo. The greatest eclipse will be near the border of Tomsk and Novosibirsk oblasts, ~200 km west of Tomsk. A partial eclipse will be visible for much of North Africa, Europe, Asia, Alaska, and northern Canada.

See also: Eclipse cycle. 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.
