An annular solar eclipse occurred on Friday, July 9, 1926. 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 the islands of Pulo Anna and Merir in Japan's South Seas Mandate (now in Palau) and Wake Island on July 10 (Saturday), and Midway Atoll on July 9 (Friday).

Solar eclipses 1924–1928[edit]

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 135[edit]

It is a part of Saros cycle 135, repeating every 18 years, 11 days, containing 71 events. The series started with partial solar eclipse on July 5, 1331. It contains annular eclipses from October 21, 1511, through February 24, 2305, hybrid eclipses on March 8, 2323, and March 18, 2341, and total eclipses from March 29, 2359, through May 22, 2449. The series ends at member 71 as a partial eclipse on August 17, 2593. The longest duration of totality will be 2 minutes, 27 seconds on May 12, 2431.

Inex series[edit]

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.

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.
