Solar eclipse of June 11, 1983

A total solar eclipse occurred at the Moon's ascending node of the orbit on June 11, 1983. 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. Occurring only 48 hours before perigee (Perigee on June 13, 1983), the Moon's apparent diameter was larger.

The path of totality went through Christmas Islands, Indonesia, Papua New Guinea, and terminated in Vanuatu. Maximum eclipse occurred off the Indonesian island of Madura. Major Indonesian cities witnessed totality, including Yogyakarta, Semarang, Surabaya, and Makassar, in addition to Port Moresby in Papua New Guinea.

Solar eclipses of 1982–1985

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 January 25, 1982 and July 20, 1982 occur in the previous lunar year eclipse set.

Saros 127

It is a part of Saros cycle 127, repeating every 18 years, 11 days, containing 82 events. The series started with partial solar eclipse on October 10, 991 AD. It contains total eclipses from May 14, 1352 through August 15, 2091. There are no annular eclipses in this series. The series ends at member 82 as a partial eclipse on March 21, 2452. The longest duration of totality was 5 minutes, 40 seconds on August 30, 1532. All eclipses in this series occurs at the Moon’s ascending node.[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.

Inex series

This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.
