# Solar eclipse of December 15, 2039

A total solar eclipse will occur at the Moon's descending node of orbit on Thursday, December 15, 2039, with a magnitude of 1.0356. 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. Occurring about 4.5 hours before perigee (on December 15, 2039, at 20:55 UTC), the Moon's apparent diameter will be larger.
The totality of the eclipse begins in the southern Pacific Ocean, passing over much of Antarctica and closely reaching the South Pole. A partial eclipse will be visible in the southern extremities of South America and Africa. It will terminate in the southern Indian Ocean several hours later.

## 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 November–December 2039 :
| November 30 Ascending node (full moon) | December 15 Descending node (new moon) |
| Partial lunar eclipse Lunar Saros 126 | Total solar eclipse Solar Saros 152 |

### Solar eclipses of 2036–2039

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 February 27, 2036 and August 21, 2036 occur in the previous lunar year eclipse set.
Solar eclipse series sets from 2036 to 2039 :
| Ascending node | Ascending node | Ascending node | Descending node | Descending node | Descending node |
| Saros | Map | Gamma | Saros | Map | Gamma |
| 117 | July 23, 2036 Partial | −1.425 | 122 | January 16, 2037 Partial | 1.1477 |

### Saros 152

This eclipse is a part of Saros series 152, repeating every 18 years, 11 days, and containing 70 events. The series started with a partial solar eclipse on July 26, 1805. It contains total eclipses from November 2, 1967 through September 14, 2490; hybrid eclipses from September 26, 2508 through October 17, 2544; and annular eclipses from October 29, 2562 through June 16, 2941. The series ends at member 70 as a partial eclipse on August 20, 3049. 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 will be produced by member 30 at 5 minutes, 16 seconds on June 9, 2328, and the longest duration of annularity will be produced by member 53 at 5 minutes, 20 seconds on February 16, 2743. All eclipses in this series occur at the Moon’s descending node of orbit.
Series members 1–22 occur between 1805 and 2200: :

### 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.
21 eclipse events between July 22, 1971 and July 22, 2047 :
| July 22 | May 9–11 | February 26–27 | December 14–15 | October 2–3 |

### 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 7, 2170 (part of Saros 164) and November 7, 2181 (part of Saros 165) are also a part of this series but are not included in the table below.
Series members between 1801 and 2105 :
| September 28, 1810 (Saros 131) | August 27, 1821 (Saros 132) | July 27, 1832 (Saros 133) | June 27, 1843 (Saros 134) | May 26, 1854 (Saros 135) |
| April 25, 1865 (Saros 136) | March 25, 1876 (Saros 137) | February 22, 1887 (Saros 138) | January 22, 1898 (Saros 139) | December 23, 1908 (Saros 140) |
| November 22, 1919 (Saros 141) | October 21, 1930 (Saros 142) | September 21, 1941 (Saros 143) | August 20, 1952 (Saros 144) | July 20, 1963 (Saros 145) |
| June 20, 1974 (Saros 146) | May 19, 1985 (Saros 147) | April 17, 1996 (Saros 148) | March 19, 2007 (Saros 149) | February 15, 2018 (Saros 150) |
| January 14, 2029 (Saros 151) | December 15, 2039 (Saros 152) | November 14, 2050 (Saros 153) | October 13, 2061 (Saros 154) | September 12, 2072 (Saros 155) |
| August 13, 2083 (Saros 156) | July 12, 2094 (Saros 157) | June 12, 2105 (Saros 158) |

### 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 :
| May 25, 1808 (Saros 144) | May 4, 1837 (Saros 145) | April 15, 1866 (Saros 146) |
| March 26, 1895 (Saros 147) | March 5, 1924 (Saros 148) | February 14, 1953 (Saros 149) |
