An annular solar eclipse will occur on Saturday, March 21, 2099. 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.

Inex series

This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.

Inex series members between 1901 and 2100:
July 20, 1925 (Saros 125)	June 30, 1954 (Saros 126)	June 11, 1983 (Saros 127)

Saros 131

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.
