An annular solar eclipse occurred at the Moon's ascending node of orbit on Thursday, January 4, 1973,[1] with a magnitude of 0.9303. 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. Occurring about 3.75 days after apogee (on December 31, 1972, at 21:50 UTC), the Moon's apparent diameter was smaller.[2]
Annularity was visible from Chile and Argentina. A partial eclipse was visible for parts of southern and central South America, Antarctica, West Africa, and Southern Africa.
