An annular solar eclipse occurred at the Moon's ascending node of orbit on Friday, February 24, 1933,[1] with a magnitude of 0.9841. 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). The Moon's apparent diameter was near the average diameter because it occurred 6.1 days after perigee (on February 18, 1933, at 10:50 UTC) and 7.25 days before apogee (on March 3, 1933, at 18:10 UTC).[2]
Annularity was visible from Chile, Argentina, Portuguese Angola (today's Angola), French Equatorial Africa (parts now belonging to R. Congo and Central African Republic), Belgian Congo (today's DR Congo), Anglo-Egyptian Sudan (parts now belonging to South Sudan and Sudan), Ethiopia, French Somaliland (today's Djibouti), southeastern Italian Eritrea (today's Eritrea), and Mutawakkilite Kingdom of Yemen, Aden Protectorate and Aden Province in British Raj (now belonging to Yemen). A partial eclipse was visible for parts of southern and central South America, Antarctica, Africa, and the Middle East.
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.[3]

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. The first and last eclipse in this sequence is separated by one synodic month.
