Solar eclipse of January 24, 1925


A total solar eclipse occurred at the Moon's descending node of orbit on Saturday, January 24, 1925, with a magnitude of 1.0304. 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 1.1 days after perigee, the Moon's apparent diameter was larger.
Totality was visible from southwestern and southeastern Ontario in Canada, Minnesota, Wisconsin, Michigan, Pennsylvania, New York, New Jersey, Connecticut, Rhode Island, and Massachusetts. A partial eclipse was visible for parts of North America, Central America, the Caribbean, northern South America, West Africa, and Western Europe.

Observations

It was seen in New York City. It was reported that those north of 96th [Street (Manhattan)|96th Street] in Manhattan saw a total solar eclipse while those south of 96th Street saw a partial eclipse.
Visual and radio observations were conducted by researchers working with Scientific American.

Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months 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.
