# Solar eclipse of October 15, 2069

A partial solar eclipse will occur at the Moon's ascending node of orbit on Tuesday, October 15, 2069, with a magnitude of 0.5298. 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 much of Antarctica.

## 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 October 2069 :
| October 15 Ascending node (new moon) | October 30 Descending node (full moon) |
| Partial solar eclipse Solar Saros 125 | Total lunar eclipse Lunar Saros 137 |

### Solar eclipses of 2069–2072

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 May 20, 2069 occurs in the previous lunar year eclipse set.
Solar eclipse series sets from 2069 to 2072 :
| Descending node | Descending node | Descending node | Ascending node | Ascending node | Ascending node |
| Saros | Map | Gamma | Saros | Map | Gamma |
| 120 | April 21, 2069 Partial | 1.0624 | 125 | October 15, 2069 Partial | −1.2524 |

### Saros 125

This eclipse is a part of Saros series 125, repeating every 18 years, 11 days, and containing 73 events. The series started with a partial solar eclipse on February 4, 1060. It contains total eclipses from June 13, 1276 through July 16, 1330; hybrid eclipses on July 26, 1348 and August 7, 1366; and annular eclipses from August 17, 1384 through August 22, 1979. The series ends at member 73 as a partial eclipse on April 9, 2358. 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 14 at 1 minutes, 11 seconds on June 25, 1294, and the longest duration of annularity was produced by member 48 at 7 minutes, 23 seconds on July 10, 1907. All eclipses in this series occur at the Moon’s ascending node of orbit.
Series members 43–64 occur between 1801 and 2200: :
| 43 | 44 | 45 |
| May 16, 1817 | May 27, 1835 | June 6, 1853 |

### 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.
23 eclipse events between August 3, 2054 and October 16, 2145 :
| August 3–4 | May 22–24 | March 10–11 | December 27–29 | October 14–16 |

### 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) |

| November 8, 2189 (Saros 136) | October 9, 2200 (Saros 137) |

### 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 :
| April 14, 1809 (Saros 116) | March 25, 1838 (Saros 117) | March 6, 1867 (Saros 118) |
