A total solar eclipse occurred at the Moon's descending node of orbit on Thursday, December 22, 1870, with a magnitude of 1.0248. 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. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Occurring about 1.4 days before perigee (on December 21, 1870, at 3:50 UTC), the Moon's apparent diameter was larger.{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=1870&n=136|publisher=timeanddate|access-date=2 September 2024}}

The path of totality was visible from parts of modern-day southern Portugal, southern Spain, northern Morocco, northern Algeria, Tunisia, Italy, Greece, northwestern Turkey, southeastern Bulgaria, southeastern Ukraine, and western Russia. A partial solar eclipse was also visible for parts of eastern Canada, Europe, North Africa, West Africa, and the Middle East.

Eclipse season

{{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.
