An annular solar eclipse occurred on February 14, 1915, also known as “The 1914 Valentine’s Day eclipse”. 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 Australia, Papua in Dutch East Indies (today's Indonesia), German New Guinea (now belonging to Papua New Guinea), and South Pacific Mandate in Japan (the parts now belonging to FS Micronesia and Marshall Islands, including Palikir).

Solar eclipses of 1913-1917[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 129[edit]

It is a part of Saros cycle 129, repeating every 18 years, 11 days, containing 80 events. The series started with partial solar eclipse on October 3, 1103. It contains annular eclipses on May 6, 1464 through March 18, 1969, hybrid eclipses on April 8, 2005 and April 20, 2023 and total eclipses from April 30, 2041 through July 26, 2185. The series ends at member 80 as a partial eclipse on February 21, 2528. The longest duration of totality was 3 minutes, 43 seconds on June 25, 2131 .[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.
