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 (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.

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.

Visual and radio observations were conducted by researchers working with Scientific American.

Shown below are two tables displaying details about this particular solar eclipse. The first table outlines times at which the Moon's penumbra or umbra attains the specific parameter, and the second table describes various other parameters pertaining to this eclipse.

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.

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.

The partial solar eclipses on March 5, 1924 and August 30, 1924 occur in the previous lunar year eclipse set, and the solar eclipses on May 19, 1928 and November 12, 1928 occur in the next lunar year eclipse set.
