Solar eclipse of May 19, 1928
A total solar eclipse occurred at the Moon's ascending node of orbit on Saturday, May 19, 1928, with a magnitude of 1.014. 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 total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Occurring about 7 hours after perigee, the Moon's apparent diameter was larger.
This solar eclipse was unusual because it was non-central while being total. While totality was not visible for any land masses, a partial eclipse was visible for extreme southern South America and Southern Africa. This was the last of 56 umbral solar eclipses in Solar Saros 117.

Eclipse season
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months 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.| May 19 Ascending node | June 3 Descending node | June 17 Ascending node |
| Total solar eclipse Solar Saros 117 | Total lunar eclipse Lunar Saros 129 | Partial solar eclipse Solar Saros 155 |
