A partial solar eclipse occurred at the Moon's descending node of orbit on Thursday, January 3, 1946,[1] with a magnitude of 0.5529. 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 partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.
This was the first of four partial solar eclipses in 1946, with the others occurring on May 30, June 29, and November 23.
A partial eclipse was visible for parts of Antarctica and extreme southern South America.

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.
| December 19 Ascending node (full moon) | January 3 Descending node (new moon) |
