Template:Short description Script error: No such module "Solar eclipse". An annular solar eclipse occurred at the Moon's descending node of orbit between Monday, January 3 and Tuesday, January 4, 1927,[1] with a magnitude of 0.9995. 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. The Moon's apparent diameter was near the average diameter because it occurred 8.6 days after apogee (on December 26, 1926, at 7:10 UTC) and 3.3 days before perigee (on January 7, 1927, at 3:00 UTC).[2]

Annularity was visible from New Zealand on January 4 (Tuesday), and Chile, Argentina, Uruguay and southern Brazil on January 3 (Monday). A partial eclipse was visible for parts of Oceania, Antarctica, and South America.

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 1924–1928

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.[4]

The partial solar eclipses on March 5, 1924 and August 30, 1924 occur in the previous lunar year eclipse set, and the solar eclipses on May 19, 1928 and November 12, 1928 occur in the next lunar year eclipse set.
