An annular solar eclipse occurred on December 25, 1935. 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. This was the 5th solar eclipse in 1935, the maximum possible. The next time this will occur is 2206.

Saros 121 edit
Solar saros 121, repeating every about 18 years, 11 days, and 8 hours, contains 71 events. The series started with a partial solar eclipse on April 25, 944. It contains total eclipses from July 10, 1070, to October 9, 1809. It contains hybrid eclipses on October 20, 1827, and October 30, 1845. It contains annular eclipses from November 11, 1863, to February 28, 2044. The series ends at member 71 as a partial eclipse on June 7, 2206. The longest total eclipse occurred on June 21, 1629, with greatest duration of totality at 6 minutes and 20 seconds. The longest annular eclipse will occur on February 28, 2044, with greatest duration of annularity at 2 minutes and 27 seconds.[2]

Tritos series edit
This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.

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.
