# Solar eclipse of October 24, 2079

An annular solar eclipse will occur at the Moon's descending node of orbit on Tuesday, October 24, 2079, with a magnitude of 0.9484. 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. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring about 5.25 days before apogee (on October 29, 2079, at 23:40 UTC), the Moon's apparent diameter will be smaller.
The path of annularity will be visible from parts of New Zealand and Antarctica. A partial solar eclipse will also be visible for parts of Oceania, Antarctica, and southern South America.

## 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 2079 :
| October 10 Ascending node (full moon) | October 24 Descending node (new moon) |
| Total lunar eclipse Lunar Saros 128 | Annular solar eclipse Solar Saros 154 |

### Solar eclipses of 2076–2079

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 6, 2076 and July 1, 2076 occur in the previous lunar year eclipse set.
Solar eclipse series sets from 2076 to 2079 :
| Ascending node | Ascending node | Ascending node | Descending node | Descending node | Descending node |
| Saros | Map | Gamma | Saros | Map | Gamma |
| 119 | June 1, 2076 Partial | −1.3897 | 124 | November 26, 2076 Partial | 1.1401 |

### Saros 154

This eclipse is a part of Saros series 154, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on July 19, 1917. It contains annular eclipses from October 3, 2043 through March 27, 2332; hybrid eclipses from April 7, 2350 through April 29, 2386; and total eclipses from May 9, 2404 through May 29, 3035. The series ends at member 71 as a partial eclipse on August 25, 3179. 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 will be produced by member 9 at 3 minutes, 41 seconds on October 13, 2061, and the longest duration of totality will be produced by member 35 at 4 minutes, 50 seconds on July 25, 2530. All eclipses in this series occur at the Moon’s descending node of orbit.
Series members 1–16 occur between 1917 and 2200: :
| 1 | 2 | 3 |

### 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 descending node.
22 eclipse events between June 1, 2011 and October 24, 2098 :

### 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 December 18, 2188 (part of Saros 164) and November 18, 2199 (part of Saros 165) are also a part of this series but are not included in the table below.
Series members between 1801 and 2134 :
| December 10, 1806 (Saros 129) | November 9, 1817 (Saros 130) | October 9, 1828 (Saros 131) | September 7, 1839 (Saros 132) | August 7, 1850 (Saros 133) |
| July 8, 1861 (Saros 134) | June 6, 1872 (Saros 135) | May 6, 1883 (Saros 136) | April 6, 1894 (Saros 137) | March 6, 1905 (Saros 138) |

### 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 24, 1819 (Saros 145) | April 3, 1848 (Saros 146) | March 15, 1877 (Saros 147) |
