An annular solar eclipse occurred on Monday, December 24, 1973. 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. Annularity was visible from southern Mexico, southwestern Nicaragua, Costa Rica including the capital city San José, Panama, Colombia including the capital city Bogotá, southern Venezuela, Brazil, southern Guyana, southern Dutch Guiana (today's Suriname), southern French Guiana, Portuguese Cape Verde (today's Cape Verde) including the capital city Praia, Mauritania including the capital city Nouakchott, Spanish Sahara (today's Western Sahara), Mali, and Algeria.

The duration of annularity at maximum eclipse (closest to but slightly shorter than the longest duration) was 12 minutes, 2.37 seconds in the Atlantic Ocean near the Brazilian coast. It was the longest annular solar eclipse until January 14, 3080, but the Solar eclipse of December 14, 1955 lasted longer. [1]

Solar eclipses of 1971–1974

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. [2]

Note: Partial solar eclipses on February 25, 1971 and August 20, 1971 occur in the next lunar year set.

Saros 141

Solar saros 141, repeating every about 18 years, 11 days, and 8 hours, contains 70 events. The series started with partial solar eclipse on May 19, 1613. It contains 41 annular eclipses from August 4, 1739, to October 14, 2460. There are no total eclipses in this series. The series ends at member 70 as a partial eclipse on June 13, 2857. The longest annular eclipse occurred on December 14, 1955, with maximum duration of annularity at 12 minutes and 9 seconds. All eclipses in this series occur at the Moon’s ascending node. [3]

Metonic series

The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's ascending node.

A total solar eclipse occurred at the Moon's ascending node on April 8, 2005. 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. This eclipse is a hybrid event, a narrow total eclipse, and beginning and ending as an annular eclipse.
