A partial solar eclipse occurred at the Moon's ascending node of orbit on Sunday, February 3, 1935,[1] with a magnitude of 0.739. 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. A partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.

This was the second of five solar eclipses in 1935, with the others occurring on January 5, June 30, July 30, and December 25. The next time this will occur is 2206.

A partial eclipse was visible for most of North America.

Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight. The first and last eclipse in this sequence is separated by one synodic month.

Solar eclipses of 1931–1935

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]

The partial solar eclipses on April 18, 1931 and October 11, 1931 occur in the previous lunar year eclipse set, and the solar eclipses on January 5, 1935 (partial), June 30, 1935 (partial), and December 25, 1935 (annular) occur in the next lunar year eclipse set.

Saros 149

This eclipse is a part of Saros series 149, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on August 21, 1664. It contains total eclipses from April 9, 2043 through October 2, 2331; hybrid eclipses from October 13, 2349 through November 3, 2385; and annular eclipses from November 15, 2403 through July 13, 2800. The series ends at member 71 as a partial eclipse on September 28, 2926. Its eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.

The longest duration of totality will be produced by member 31 at 4 minutes, 10 seconds on July 17, 2205, and the longest duration of annularity will be produced by member 62 at 5 minutes, 6 seconds on June 21, 2764. All eclipses in this series occur at the Moon’s ascending node of orbit.[4]

Metonic series

The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's ascending node.

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.

The partial solar eclipse on October 24, 2098 (part of Saros 164) is also a part of this series but is not included in the table below.

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.
