An annular solar eclipse occurred at the Moon's ascending node of orbit on Tuesday, January 5, 1954,{{cite web|title=January 5, 1954 Annular Solar Eclipse|url=https://www.timeanddate.com/eclipse/solar/1954-january-5|publisher=timeanddate|access-date=5 August 2024}} with a magnitude of 0.972. 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. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. The Moon's apparent diameter was near the average diameter because it occurred 7.5 days after apogee (on December 28, 1953, at 15:10 UTC) and 5.3 days before perigee (on January 10, 1954, at 9:40 UTC).{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=1954&n=136|publisher=timeanddate|access-date=5 August 2024}}

Annularity was visible from a part of Antarctica. A partial eclipse was visible for parts of Antarctica and Oceania.

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.
