Solar eclipse of August 20, 1952
Template:Short description Script error: No such module "Solar eclipse". An annular solar eclipse occurred at the Moon's descending node of orbit on Wednesday, August 20, 1952,[1] with a magnitude of 0.942. 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 1.2 days after apogee (on August 19, 1952, at 12:00 UTC), the Moon's apparent diameter was smaller.[2]
Annularity was visible from Peru including the capital city Lima, northeastern Chile, Bolivia including the constitutional capital Sucre and seat of government La Paz, Argentina, Paraguay, southern Brazil and Uruguay. A partial eclipse was visible for most of Central America, the Caribbean, 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 1950–1953
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 eclipse on July 11, 1953 occurs in the next lunar year eclipse set.
