Solar eclipse of July 10, 1907

An annular solar eclipse occurred on July 10, 1907. 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 Chile, Bolivia including its capital Sucre, and Brazil. The green line means eclipse begins or ends at sunrise or sunset. The magenta line means mid eclipse at sunrise or sunset, or northern or southern penumbra limits. The green point means eclipse obscuration of 50%. The red line means antumbral northern and southern limits.

Solar eclipses 1906–1909

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]

Saros 125

Solar saros 125, repeating every about 18 years and 11 days, contains 73 events. The series started with a partial solar eclipse on February 4, 1060. It has total eclipses from June 13, 1276, to July 16, 1330. It has hybrid eclipses on July 26, 1348, and August 7, 1366, and annular eclipses from August 17, 1384, to August 22, 1979. The series ends at member 73 as a partial eclipse on April 9, 2358. The longest total eclipse occurred on June 25, 1294, at 1 minute and 11 seconds; the longest annular eclipse occurred on July 10, 1907, at 7 minutes and 23 seconds.[2]

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.
