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 (on January 23, 1925, at 13:30 UTC), the Moon's apparent diameter was larger.
Totality was visible from southwestern and southeastern Ontario in Canada (including Toronto and Niagara Falls), Minnesota, Wisconsin, Michigan, Pennsylvania, New York (including the northern part of New York City), 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 in Manhattan saw a total solar eclipse while those south of 96th Street saw a partial eclipse.Solar Eclipses in History by Ken Poshedly
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 (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.
