An annular solar eclipse occurred on January 15–16, 1991. 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. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Annularity was visible in southwestern West Australia, Tasmania, New Zealand and French Polynesia. It was visible over Australia as a partial solar eclipse at sunrise on January 16.

Metonic series[edit]
The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's ascending node.
21 eclipse events, progressing from south to north between June 10, 1964, and August 21, 2036 | ||||
