A total solar eclipse occurred on August 7, 1869. 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. It path of toality was visible from eastern Russia, Alaska, across Canada, and the northeastern United States. A partial eclipse occurred across all of North America.
In 1869, astronomer and explorer George Davidson made a scientific trip to the Chilkat Valley of Alaska. He told the Chilkat Indians that he was especially anxious to observe a total eclipse of the sun that was predicted to occur the following day, August 7. This prediction was considered to have saved them from an attack.
It is a part of solar Saros 143.
