A total solar eclipse occurred on Tuesday, June 30, 1992. 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. Totality was visible in southeastern Uruguay and southern tip of Rio Grande do Sul, Brazil.

Saros 146[edit]

It is a part of Saros cycle 146, repeating every 18 years, 11 days, containing 76 events. The series started with partial solar eclipse on September 19, 1541. It contains total eclipses from May 29, 1938 through October 7, 2154, hybrid eclipses from October 17, 2172 through November 20, 2226, and annular eclipses from December 1, 2244 through August 10, 2659. The series ends at member 76 as a partial eclipse on December 29, 2893. The longest duration of totality was 5 minutes, 21 seconds on June 30, 1992.

Inex series[edit]

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. In the 19th century:

  • Solar saros 140: total solar eclipse of October 29, 1818
  • Solar saros 141: annular solar eclipse of October 9, 1847
  • Solar saros 142: total solar eclipse of September 17, 1876

In the 22nd century:

  • Solar saros 150: partial solar eclipse of April 11, 2108
  • Solar saros 151: annular solar eclipse of March 21, 2137
  • Solar saros 152: total solar eclipse of March 2, 2166
  • Solar saros 153: annular solar eclipse February 10, 2195

Tritos series[edit]

This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.

Metonic series[edit]

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 descending node.

22 eclipse events between September 12, 1931 and July 1, 2011.
