Solar eclipse of January 25, 1944
Template:Short description Script error: No such module "Solar eclipse". A total solar eclipse occurred at the Moon's descending node of orbit on Tuesday, January 25, 1944,[1] with a magnitude of 1.0428. 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. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Occurring about 20 hours before perigee (on January 26, 1944, at 11:30 UTC), the Moon's apparent diameter was larger.[2]
Totality was visible from Peru, Brazil, British Sierra Leone (today's Sierra Leone), and French West Africa (the parts now belonging to Guinea, Mali, Burkina Faso and Niger, including Guinean capital Conakry). A partial eclipse was visible for parts of southern North America, Central America, the Caribbean, South America, Western Europe, West Africa, and Central Africa.
Observations
The National Astronomical Observatory in Tacubaya, Mexico sent a team to Chiclayo, Peru. The weather was clear during the eclipse, and because totality occurred shortly after sunrise with a relatively low solar zenith angle, the boundary between the corona and the background of the sky was not so obvious. Most images were taken successfully except for one with the long focus camera.[3]

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 1942–1946
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.[5]
The partial solar eclipses on March 16, 1942 and September 10, 1942 occur in the previous lunar year eclipse set, and the partial solar eclipses on May 30, 1946 and November 23, 1946 occur in the next lunar year eclipse set.

Saros 130
This eclipse is a part of Saros series 130, repeating every 18 years, 11 days, and containing 73 events. The series started with a partial solar eclipse on August 20, 1096. It contains total eclipses from April 5, 1475 through July 18, 2232. There are no annular or hybrid eclipses in this set. The series ends at member 73 as a partial eclipse on October 25, 2394. 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 30 at 6 minutes, 41 seconds on July 11, 1619. All eclipses in this series occur at the Moon’s descending node of orbit.[6]
