Solar eclipse of July 30, 1916
Template:Short description Script error: No such module "Solar eclipse". An annular solar eclipse occurred at the Moon's descending node of orbit on Sunday, July 30, 1916,[1][2][3] with a magnitude of 0.9447. 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. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring 1.75 days after apogee (on July 28, 1916, at 8:30 UTC), the Moon's apparent diameter was smaller.[4]
Annularity was visible from only one country, Australia. A partial eclipse was visible for parts of Southeast Asia, Australia, Oceania, and Antarctica.

Eclipse season
Script error: No such module "Labelled list hatnote". 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.

Solar eclipses of 1913–1917
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.[6]
The partial solar eclipses on April 6, 1913 and September 30, 1913 occur in the previous lunar year eclipse set, and the solar eclipses on December 24, 1916 (partial), June 19, 1917 (partial), and December 14, 1917 (annular) occur in the next lunar year eclipse set.
