# Solar eclipse of January 3, 1908

A total solar eclipse occurred at the Moon's descending node of orbit between Friday, January 3 and Saturday, January 4, 1908, with a magnitude of 1.0437. 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 14 hours before perigee (on January 4, 1908, at 12:30 UTC), the Moon's apparent diameter was larger.
Totality was visible from Ebon Atoll in German New Guinea (now in Marshall Islands), British Western Pacific Territories (the part now belonging to Kiribati), Line Islands (now in Kiribati), Phoenix Islands (now in Kiribati) on January 4 (Saturday), and Costa Rica on January 3 (Friday). A partial eclipse was visible for parts of northern Oceania, Hawaii, southern North America, Central America, the western Caribbean, and western South America.

## Observations

The eclipse was observed by astronomer William Wallace Campbell of Lick Observatory, viewed from Flint Island, Kiribati, an uninhabited island in the Line Islands. The team of Lick Observatory departed from San Francisco on November 22, 1907, and arrived in Papeete, Tahiti Island, the capital of French Polynesia on December 4. After making preparations of supplies and logistics personnel, it departed again on the evening of December 7 and arrived at Flint Island on the afternoon of the 9:
Astronomers from the Royal Astronomical Society, Sydney Observatory and a party from Australia and New Zealand which included Francis McClean and Henry Winkelmann also observed the total eclipse near the observation site of Lick Observatory. The team successfully took images of the corona.

## 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 1908 :
| January 3 Descending node (new moon) | January 18 Ascending node (full moon) |
| Total solar eclipse Solar Saros 130 | Penumbral lunar eclipse Lunar Saros 142 |

### Solar eclipses of 1906–1909

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 23, 1906 and August 20, 1906 occur in the previous lunar year eclipse set.
Solar eclipse series sets from 1906 to 1909 :

### Saros 130

This eclipse is a part of Saros series 130, repeating every 18 years, 11 days, and containing 73 events. The series started with a partial solar eclipse on August 20, 1096. It contains total eclipses from April 5, 1475 through July 18, 2232. There are no annular or hybrid eclipses in this set. The series ends at member 73 as a partial eclipse on October 25, 2394. 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 30 at 6 minutes, 41 seconds on July 11, 1619. All eclipses in this series occur at the Moon’s descending node of orbit.
Series members 41–62 occur between 1801 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.
22 eclipse events between March 16, 1866 and August 9, 1953 :
| March 16–17 | January 1–3 | October 20–22 | August 9–10 | May 27–29 |

### 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 :
| October 9, 1809 (Saros 121) | September 7, 1820 (Saros 122) | August 7, 1831 (Saros 123) | July 8, 1842 (Saros 124) | June 6, 1853 (Saros 125) |

### 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 :
