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.

This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[1] This semester series contains only 7 eclipses.

Saros 131[edit]

It is a part of Saros cycle 131, repeating every 18 years, 11 days, containing 70 events. The series started with partial solar eclipse on August 1, 1125. It contains total eclipses from March 27, 1522 through May 30, 1612 and hybrid eclipses from June 10, 1630 through July 24, 1702, and annular eclipses from August 4, 1720 through June 18, 2243. The series ends at member 70 as a partial eclipse on September 2, 2369. The longest duration of totality was only 58 seconds on May 30, 1612. All eclipses in this series occurs at the Moon’s ascending node.

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.
