Solar eclipse of August 28, 1802

An annular solar eclipse occurred at the Moon's descending node of orbit on Saturday, August 28, 1802, with a magnitude of 0.9367. 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 only about 3 hours after apogee (on August 28, 1802, at 4:30 UTC), the Moon's apparent diameter was smaller.{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=1802&n=136|publisher=timeanddate|access-date=28 September 2024}}

The path of annularity was visible from parts of modern-day Greenland, Svalbard, Russia, Mongolia, China, and the Ryukyu Islands. A partial solar eclipse was also visible for parts of Greenland, northern Canada, Europe, Asia, and western Alaska.{{cite web|title=Solar eclipse of August 28, 1802|url=http://eclipse.gsfc.nasa.gov/5MCSEmap/1801-1900/1802-08-28.gif|publisher=NASA|accessdate=June 15, 2012}}

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.
