# Solar eclipse of June 21, 1982

A partial solar eclipse occurred at the Moon's ascending node of orbit on Monday, June 21, 1982, with a magnitude of 0.6168. 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 partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.
This was the second of four partial solar eclipses in 1982, with the others occurring on January 25, July 20, and December 15.
A partial eclipse was visible for parts of Southern Africa.

## Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight. The first and last eclipse in this sequence is separated by one synodic month.
Eclipse season of June–July 1982 :
| June 21 Ascending node (new moon) | July 6 Descending node (full moon) | July 20 Ascending node (new moon) |
| Partial solar eclipse Solar Saros 117 | Total lunar eclipse Lunar Saros 129 | Partial solar eclipse Solar Saros 155 |

### 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.
The partial solar eclipses on January 25, 1982 and July 20, 1982 occur in the previous lunar year eclipse set.
Solar eclipse series sets from 1982 to 1985 :
| Ascending node | Ascending node | Ascending node | Descending node | Descending node | Descending node |
| Saros | Map | Gamma | Saros | Map | Gamma |
| 117 | June 21, 1982 Partial | −1.2102 | 122 | December 15, 1982 Partial | 1.1293 |

### Saros 117

This eclipse is a part of Saros series 117, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on June 24, 792 AD. It contains annular eclipses from September 18, 936 AD through May 14, 1333; hybrid eclipses from May 25, 1351 through July 8, 1423; and total eclipses from July 18, 1441 through May 19, 1928. The series ends at member 71 as a partial eclipse on August 3, 2054. Its eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.
The longest duration of annularity was produced by member 16 at 9 minutes, 26 seconds on December 3, 1062, and the longest duration of totality was produced by member 62 at 4 minutes, 19 seconds on April 26, 1892. All eclipses in this series occur at the Moon’s ascending node of orbit.
Series members 57–71 occur between 1801 and 2054: :
| 57 | 58 | 59 |
| March 4, 1802 | March 14, 1820 | March 25, 1838 |

### 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.
21 eclipse events between June 21, 1982 and June 21, 2058 :

### Tritos series

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.
The partial solar eclipses on March 27, 1884 (part of Saros 108) and December 24, 1916 (part of Saros 111) are also a part of this series but are not included in the table below.
Series members between 1971 and 2200 :
| July 22, 1971 (Saros 116) | June 21, 1982 (Saros 117) | May 21, 1993 (Saros 118) | April 19, 2004 (Saros 119) | March 20, 2015 (Saros 120) |
| February 17, 2026 (Saros 121) | January 16, 2037 (Saros 122) | December 16, 2047 (Saros 123) | November 16, 2058 (Saros 124) | October 15, 2069 (Saros 125) |
| September 13, 2080 (Saros 126) | August 15, 2091 (Saros 127) | July 15, 2102 (Saros 128) | June 13, 2113 (Saros 129) | May 14, 2124 (Saros 130) |

### 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.
Series members between 1801 and 2200 :
| October 19, 1808 (Saros 111) | | |
| August 20, 1895 (Saros 114) | July 31, 1924 (Saros 115) | July 11, 1953 (Saros 116) |
