A total solar eclipse occurred on July 29, 1878. 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, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across the surface of the Earth, while a partial solar eclipse will be visible over a region thousands of kilometres wide.
This eclipse was visible at sunrise at a path across northeastern Asia and passed across Alaska, western Canada, and the United States from Wyoming through Texas.
