A total solar eclipse occurred on October 23, 1976. 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 total solar eclipse began at sunrise in Tanzania near the border with Burundi, with the path of totality passing just north of the large Tanzanian city of Dar es Salaam. It then crossed the Indian Ocean before making landfall in southeastern Australia. The largest city that saw totality was Melbourne. After leaving the Australian mainland, the path of totality left the Earth's surface just north of the north island of New Zealand.
