# Solar eclipse of January 16, 2056

An annular solar eclipse will occur at the Moon's descending node of orbit between Sunday, January 16 and Monday, January 17, 2056, with a magnitude of 0.9759. 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. The Moon's apparent diameter will be near the average diameter because it will occur 6.25 days after perigee (on January 10, 2056, at 16:50 UTC) and 7.2 days before apogee (on January 24, 2056, at 2:20 UTC).
The path of annularity will be visible from parts of the Marshall Islands, northern Mexico, and Texas. A partial solar eclipse will also be visible for parts of Oceania, Hawaii, western and central North America, and Central 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 January–February 2056 :
| January 16 Descending node (new moon) | February 1 Ascending node (full moon) |
| Annular solar eclipse Solar Saros 132 | Penumbral lunar eclipse Lunar Saros 144 |

### Solar eclipses of 2054–2058

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 March 9, 2054 and September 2, 2054 occur in the previous lunar year eclipse set, and the partial solar eclipses on May 22, 2058 and November 16, 2058 occur in the next lunar year eclipse set.
Solar eclipse series sets from 2054 to 2058 :
| Ascending node | Ascending node | Ascending node | Descending node | Descending node | Descending node |
| Saros | Map | Gamma | Saros | Map | Gamma |
| 117 | August 3, 2054 Partial | −1.4941 | 122 | January 27, 2055 Partial | 1.155 |

### Saros 132

This eclipse is a part of Saros series 132, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on August 13, 1208. It contains annular eclipses from March 17, 1569 through March 12, 2146; hybrid eclipses on March 23, 2164 and April 3, 2182; and total eclipses from April 14, 2200 through June 19, 2308. The series ends at member 71 as a partial eclipse on September 25, 2470. 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 25 at 6 minutes, 56 seconds on May 9, 1641, and the longest duration of totality will be produced by member 61 at 2 minutes, 14 seconds on June 8, 2290. All eclipses in this series occur at the Moon’s descending node of orbit.

### 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 12, 2029 and November 4, 2116 :

### 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 1801 and 2200 :
| January 1, 1805 (Saros 109) | | October 31, 1826 (Saros 111) | | August 28, 1848 (Saros 113) |
| July 29, 1859 (Saros 114) | June 28, 1870 (Saros 115) | May 27, 1881 (Saros 116) | April 26, 1892 (Saros 117) | March 29, 1903 (Saros 118) |

### 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 :
