A total solar eclipse occurred on 28 April 1911.[1][2][3] 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. Totality was visible from southeastern tip of Australia, Tonga, American Samoa and Cook Islands. Places west of International Date Line witnessed the eclipse on Saturday 29 April 1911.
