A partial solar eclipse occurred at the Moon's ascending node of orbit on Sunday, June 17, 1928,[1] 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.
A partial eclipse was visible for parts of the northern Soviet Union. This is the 1st solar eclipse of Solar Saros 155, and this is the next saros cycle to begin after the partial solar eclipse of July 19, 1917 (part of Solar Saros 154).
Shown below are two tables displaying details about this particular solar eclipse. The first table outlines times at which the moon's penumbra or umbra attains the specific parameter, and the second table describes various other parameters pertaining to this eclipse.[2]

See also: Eclipse cycle. 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.
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.
