Solar eclipse of November 11, 1863


An annular solar eclipse occurred at the Moon's ascending node of orbit on Wednesday, November 11, 1863, with a magnitude of 0.9943. 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. An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring about 3.7 days before perigee, the Moon's apparent diameter was larger.
The path of annularity was visible from parts of Antarctica. A partial solar eclipse was also visible for parts of Southern Africa, Antarctica, and southern Australia.

Description

The eclipse took place in Africa including Namacqualand, Bechuanaland South Africa, Basutoland, Zululand and portions of Swaziland. The rest took place in the South Atlantic up to hundreds of kilometers offshore from South America except for Tierra del Fuego which was included and included the islands, the Indian Ocean, all of Antarctica which many areas had a 24-hour daylight that time, the southernmost areas of Australia along with Tasmania and the southernmost parts of the Pacific Ocean.
As the Moon moved towards the left on Earth in Africa, at the peninsular portion, it was seen as it was moved towards the bottom right, then right then top as the axis spun at around the 71st parallel south.
The eclipse started at sunrise close to South America and finished at sunset in Australia, 70% at the Antarctic shores at the Indian Ocean.
It showed up to 30% obscuration in the area of Cape Town and Cape Agulhas up to 99% inside the maximum width of band. The greatest eclipse was in the middle of Antarctica east of the Prime Meridian at 75.4 S, 15.1 E at 8:09 UTC and lasted for 22 seconds, the maximum width of band was only 42 km, the view around it was partly dark even inside the clouds.
The subsolar marking was east of Madagascar and close to the Mascarene Islands.

Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months 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.
