Solar eclipse of January 16, 1972

An annular solar eclipse occurred on January 16, 1972. 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 areas included were the whole of Antarctica, a part of the southernmost portion of South America much of it in Argentina and a smaller part of Chile, much of it in the region of Patagonia, also it included New Amsterdam and the southern islands of the Indian Ocean,. The annular eclipse took place in western, southern and eastern Antarctica with its greatest eclipse in the eastcentral portion of the continent near the 75th parallel. The eclipse's edges were in Réunion and Mauritius, the eclipse was close to the island of Madagascar. The subsolar portion was in northcentral South West Africa (now Namibia).

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.[1]

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

Saros 121

Solar saros 121, repeating every about 18 years, 11 days, and 8 hours, contains 71 events. The series started with a partial solar eclipse on April 25, 944. It contains total eclipses from July 10, 1070, to October 9, 1809. It contains hybrid eclipses on October 20, 1827, and October 30, 1845. It contains annular eclipses from November 11, 1863, to February 28, 2044. The series ends at member 71 as a partial eclipse on June 7, 2206. The longest total eclipse occurred on June 21, 1629, with greatest duration of totality at 6 minutes and 20 seconds. The longest annular eclipse will occur on February 28, 2044, with greatest duration of annularity at 2 minutes and 27 seconds.[2]

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.
