# Solar eclipse of May 26, 1854

An annular solar eclipse occurred at the Moon's ascending node of orbit on Friday, May 26, 1854, with a magnitude of 0.9551. 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 3.2 days before apogee (on May 30, 1854, at 2:25 UTC), the Moon's apparent diameter was smaller.
The path of annularity was visible from parts of the modern-day Marshall Islands, southern Canada, Washington, northern Idaho, northern Montana, northern North Dakota, Minnesota, the upper peninsula of Michigan, New York, Vermont, New Hampshire, Massachusetts, and Maine. A partial solar eclipse was also visible for parts of Northeast Asia, northern Oceania, Hawaii, North America, Central America, the Caribbean, far northern South America, and northern Scandinavia.

## Visibility

The annular path crossed close to the boundary between the United States and Canada.

## 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 May 1854 :
| May 12 Descending node (full moon) | May 26 Ascending node (new moon) |
| Partial lunar eclipse Lunar Saros 109 | Annular solar eclipse Solar Saros 135 |

### Solar eclipses of 1852–1855

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 January 21, 1852 occurs in the previous lunar year eclipse set.
Solar eclipse series sets from 1852 to 1855 :
| Ascending node | Ascending node | Ascending node | Descending node | Descending node | Descending node |
| Saros | Map | Gamma | Saros | Map | Gamma |
| 115 | June 17, 1852 Partial | −1.1111 | 120 | December 11, 1852 Total | 0.8551 |

### Saros 135

This eclipse is a part of Saros series 135, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on July 5, 1331. It contains annular eclipses from October 21, 1511 through February 24, 2305; hybrid eclipses on March 8, 2323 and March 18, 2341; and total eclipses from March 29, 2359 through May 22, 2449. The series ends at member 71 as a partial eclipse on August 17, 2593. 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 16 at 10 minutes, 41 seconds on December 24, 1601, and the longest duration of totality will be produced by member 62 at 2 minutes, 27 seconds on May 12, 2431. All eclipses in this series occur at the Moon’s ascending 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 ascending node.
25 eclipse events between March 14, 1801 and August 7, 1888 :
| March 14–15 | December 31–January 1 | October 19–20 | August 7 | May 26–27 |

### 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) |

### 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 :
| June 16, 1825 (Saros 134) | May 26, 1854 (Saros 135) | May 6, 1883 (Saros 136) |
