A partial solar eclipse occurred at the Moon's descending node of orbit on Sunday, June 30, 1935,^[1] with a magnitude of 0.3375. 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 third of five solar eclipses in 1935, with the others occurring on January 5, February 3, July 30, and December 25. The next time this will occur is 2206.

A partial eclipse was visible for parts of Northern Europe, the northern Soviet Union, and Greenland.

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 1935–1938

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 February 3, 1935 and July 30, 1935 occur in the previous lunar year eclipse set.

Saros 116

This eclipse is a part of Saros series 116, repeating every 18 years, 11 days, and containing 70 events. The series started with a partial solar eclipse on June 23, 727 AD. It contains annular eclipses from October 10, 907 AD through May 6, 1845. There are no hybrid or total eclipses in this set. The series ends at member 70 as a partial eclipse on July 22, 1971. 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 annularity was produced by member 51 at 12 minutes, 2 seconds on December 25, 1628. All eclipses in this series occur at the Moon’s descending node of orbit.^[4]

Series members 61–70 occur between 1801 and 1971:

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 descending 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.

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.
