Solar eclipse of August 29, 1867
Template:Short description Script error: No such module "Solar eclipse". A total solar eclipse occurred at the Moon's ascending node of orbit on Thursday, August 29, 1867, with a magnitude of 1.0344. 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 2.5 days after perigee (on August 27, 1867, at 2:00 UTC), the Moon's apparent diameter was larger.[1]
The path of totality was visible from parts of modern-day Chile, Argentina, and Uruguay. A partial solar eclipse was also visible for parts of South America, Southern Africa, and Antarctica.

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 1866–1870
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.[4]
The partial solar eclipses on April 15, 1866 and October 8, 1866 occur in the previous lunar year eclipse set, and the solar eclipses on June 28, 1870 (partial) and December 22, 1870 (total) occur in the next lunar year eclipse set.
