# Solar eclipse of March 21, 2080

A partial solar eclipse will occur at the Moon's ascending node of orbit on Thursday, March 21, 2080, with a magnitude of 0.8734. 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.
The partial solar eclipse will be visible for parts of Antarctica and 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.
Eclipse season of March–April 2080 :
| March 21 Ascending node (new moon) | April 4 Descending node (full moon) |
| Partial solar eclipse Solar Saros 121 | Total lunar eclipse Lunar Saros 133 |

### Solar eclipses of 2080–2083

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 eclipse on July 15, 2083 occurs in the next lunar year eclipse set.
Solar eclipse series sets from 2080 to 2083 :
| Ascending node | Ascending node | Ascending node | Descending node | Descending node | Descending node |
| Saros | Map | Gamma | Saros | Map | Gamma |
| 121 | March 21, 2080 Partial | −1.0578 | 126 | September 13, 2080 Partial | 1.0723 |

### Saros 121

This eclipse is a part of Saros series 121, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on April 25, 944 AD. It contains total eclipses from July 10, 1070 through October 9, 1809; hybrid eclipses on October 20, 1827 and October 30, 1845; and annular eclipses from November 11, 1863 through February 28, 2044. The series ends at member 71 as a partial eclipse on June 7, 2206. 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 totality was produced by member 39 at 6 minutes, 20 seconds on June 21, 1629, and the longest duration of annularity will be produced by member 62 at 2 minutes, 27 seconds on February 28, 2044. All eclipses in this series occur at the Moon’s ascending node of orbit.
Series members 49–70 occur between 1801 and 2200: :
| 49 | 50 | 51 |
| October 9, 1809 | October 20, 1827 | October 30, 1845 |

### 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.
22 eclipse events between June 1, 2076 and October 27, 2163 :
| June 1–3 | March 21–22 | January 7–8 | October 26–27 | August 14–15 |

### 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.
Series members between 2036 and 2200 :
| July 23, 2036 (Saros 117) | June 23, 2047 (Saros 118) | May 22, 2058 (Saros 119) | April 21, 2069 (Saros 120) | March 21, 2080 (Saros 121) |
| February 18, 2091 (Saros 122) | January 19, 2102 (Saros 123) | December 19, 2112 (Saros 124) | November 18, 2123 (Saros 125) | October 17, 2134 (Saros 126) |
| September 16, 2145 (Saros 127) | August 16, 2156 (Saros 128) | July 16, 2167 (Saros 129) | June 16, 2178 (Saros 130) | May 15, 2189 (Saros 131) |
| April 14, 2200 (Saros 132) |

### 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 :
| September 19, 1819 (Saros 112) | August 28, 1848 (Saros 113) | August 9, 1877 (Saros 114) |
