A total solar eclipse occurred at the Moon's descending node of orbit on Wednesday, July 18, 1860, with a magnitude of 1.0500.

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 2.2 days before perigee (on July 20, 1860, at 19:15 UTC), the Moon's apparent diameter was larger.

[1] The path of totality was visible from parts of modern-day northwestern Oregon, Washington, northern Idaho, northwestern Montana, Canada, Spain, Algeria, Tunisia, Libya, Egypt, Sudan, and Eritrea.

Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee).
