Solar eclipse of January 25, 1963
Template:Short description Script error: No such module "Solar eclipse". An annular solar eclipse occurred at the Moon's descending node of orbit on Friday, January 25, 1963,[1] with a magnitude of 0.9951. 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 8.2 days after apogee (on January 17, 1963, at 8:00 UTC) and 3.7 days before perigee (on January 29, 1963, at 7:20 UTC).[2]
The moon's apparent diameter was 4.8 arcseconds larger than the July 20, 1963 total solar eclipse. This was an annular solar eclipse because it occurred in January and the earth is near its perihelion (closest approach to the Sun) in January.
The path of annularity crossed Chile, Argentina, South Africa, southern Basutoland (today's Lesotho) and Malagasy Republic (today's Madagascar). A partial eclipse was visible for parts of southern and central South America, Antarctica, Southern Africa, and Eastern Africa.

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 1961–1964
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 June 10, 1964 and December 4, 1964 occur in the next lunar year eclipse set.
