A partial solar eclipse occurred at the Moon's ascending node of orbit on Sunday, June 17, 1928, with a magnitude of 0.0375. 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 is the 1st solar eclipse of Solar Saros 155, and this is the new saros to begin since the partial solar eclipse of July 19, 1917.

Solar eclipses of 1924–1928

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]

The partial solar eclipses on March 5, 1924 and August 30, 1924 occur in the previous lunar year eclipse set, and the solar eclipses on May 19, 1928 and November 12, 1928 occur in the next lunar year eclipse set.

Saros 155

This eclipse is a part of Saros series 155, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on June 17, 1928. It contains total eclipses from September 12, 2072 through August 30, 2649; hybrid eclipses from September 10, 2667 through October 2, 2703; and annular eclipses from October 13, 2721 through May 8, 3064. The series ends at member 71 as a partial eclipse on July 24, 3190. 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 14 at 4 minutes, 5 seconds on November 6, 2162, and the longest duration of annularity will be produced by member 63 at 5 minutes, 31 seconds on April 28, 3046. All eclipses in this series occur at the Moon’s ascending node of orbit.^[2]

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.

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.

The partial solar eclipse on December 18, 2188 (part of Saros 164) is also a part of this series but is not included in the table below.
