Solar eclipse of January 25, 1944

Total eclipse

Summary

Total eclipse

FieldValue
previousSolar eclipse of August 1, 1943
nextSolar eclipse of July 20, 1944

A total solar eclipse occurred at the Moon's descending node of orbit on Tuesday, January 25, 1944, 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.

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.

Eclipse season

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.
