A total lunar eclipse occurred at the Moon’s ascending node of orbit on Sunday, June 3, 1928,[1] with an umbral magnitude of 1.2421. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow. Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. A total lunar eclipse can last up to nearly two hours, while a total solar eclipse lasts only a few minutes at any given place, because the Moon's shadow is smaller. Occurring only about 2.1 days after apogee (on June 1, 1928, at 9:00 UTC), the Moon's apparent diameter was smaller.[2]
This lunar eclipse was the third of a tetrad, with four total lunar eclipses in series, the others being on June 15, 1927; December 8, 1927; and November 27, 1928.
Visibility
The eclipse was completely visible over Australia, Antarctica, and the central Pacific Ocean, seen rising over south and east Asia and setting over North and South America.[3]

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.

Lunar eclipses of 1926–1929
This eclipse is a member of a semester series. An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[5]
The penumbral lunar eclipses on January 28, 1926 and July 25, 1926 occur in the previous lunar year eclipse set.

Half-Saros cycle
A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[6] This lunar eclipse is related to two total solar eclipses of Solar Saros 136.
