An annular solar eclipse occurred at the Moon's descending node of orbit on Friday, January 25, 1963, 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 path of annularity crossed Chile, Argentina, South Africa, southern Basutoland (today's Lesotho) and Malagasy Republic (today's Madagascar). Occurring 3.7 days before perigee (on January 29, 1963), the Moon's apparent diameter was larger. The moon was 374,860 km (232,927 mi) from the Earth.
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 in January the earth is near its perihelion (closest approach to the Sun).

Solar eclipses of 1961–1964[edit]
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.[1]
The partial solar eclipses on June 10, 1964 and December 4, 1964 occur in the next lunar year eclipse set.

Saros 140[edit]
This eclipse is a part of Saros series 140, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on April 16, 1512. It contains total eclipses from July 21, 1656 through November 9, 1836; hybrid eclipses from November 20, 1854 through December 23, 1908; and annular eclipses from January 3, 1927 through December 7, 2485. The series ends at member 71 as a partial eclipse on June 1, 2774. Its eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.
The longest duration of totality was produced by member 11 at 4 minutes, 10 seconds on August 12, 1692, and the longest duration of annularity will be produced by member 53 at 7 minutes, 35 seconds on November 15, 2449. All eclipses in this series occur at the Moon’s descending node of orbit.[2]

Metonic series[edit]
The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days).
