ON THE MAY 1928 SOLAR ECLIPSE

A total solar eclipse occurred on May 19, 1928. 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, and turning day into darkness. Totality occurs in a narrow path across the Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometers wide.

While it was a total solar eclipse, it was a non-central total eclipse. This was the last of 56 umbral solar eclipses of Solar Saros 117. The 1st was in 936 AD and the 56th was in 1928. The total duration is 992 years.

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. (Wikipedia).
