Solar eclipse of August 29, 1867
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, the Moon's apparent diameter was larger.
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.
Observations
José J. Vergara and Luis Grosch observed the eclipse from a small hill close to Santiago.Eclipse details

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.| August 29 Ascending node | September 14 Descending node |
| Total solar eclipse Solar Saros 123 | Partial lunar eclipse Lunar Saros 135 |
