An annual solar eclipse occurred on November 12, 1947. 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.

Each member 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.

Saros 132
It is a part of Saros cycle 132, repeating every 18 years, 11 days, containing 71 events. The series started with partial solar eclipse on August 13, 1208. It contains annular eclipses from March 17, 1569 through March 12, 2146, hybrid on March 23, 2164 and April 3, 2183 and total eclipses from April 14, 2200 through June 19, 2308. The series ends at member 71 as a partial eclipse on September 25, 2470. The longest duration of annular was 4 minutes, 2 seconds on 1965 Nov 23, and totality will be 2 minutes, 14 seconds on May 27, 2272.[1]
Series members 40-50 occur between 1901 and 2100:
Tritos series
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.
Series members between 1901 and 2100 are:
