An annular solar eclipse occurred on March 29, 1903.^[1][2] 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 from China (now northwestern China, Mongolia and northeastern China), Russia on March 29 (Sunday), and Northern Canada on March 28 (Saturday).

Solar eclipses 1902–1907

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.^[3]

Saros 118

It is a part of Saros cycle 118, repeating every 18 years, 11 days, containing 72 events. The series started with partial solar eclipse on May 24, 803 AD. It contains total eclipses from August 19, 947 AD through October 25, 1650, hybrid eclipses on November 4, 1668, and November 15, 1686, and annular eclipses from November 27, 1704, through April 30, 1957. The series ends at member 72 as a partial eclipse on July 15, 2083. The longest duration of total was 6 minutes, 59 seconds on May 16, 1398.

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.
