A total solar eclipse occurred on September 9, 1904. 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. Totality was visible from German New Guinea (the part now belonging to Marshall Islands) on September 10 and Chile on September 9.

Solar eclipses 1902-1907[edit]

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.[1]

Saros 133[edit]

Solar Saros 133, repeating every 18 years, 11 days, contains 72 events. The series started with a partial solar eclipse on July 13, 1219. It contains annular eclipses from November 20, 1435, through January 13, 1526, with a hybrid eclipse on January 24, 1544. It has total eclipses from February 3, 1562, through June 21, 2373. The series ends at member 72 as a partial eclipse on September 5, 2499. The longest duration of totality was 6 minutes, 50 seconds on August 7, 1850.[2] The total eclipses of this saros series are getting shorter and farther south with each iteration. All eclipses in this series occurs at the Moon’s ascending node.

Inex series[edit]

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. In the 18th century:

• Solar Saros 127: Total Solar Eclipse of 1731 Jan 08

• Solar Saros 128: Annular Solar Eclipse of 1759 Dec 19

• Solar Saros 129: Annular Solar Eclipse of 1788 Nov 27

In the 23rd century:

• Solar Saros 144: Annular Solar Eclipse of 2223 Feb 01

• Solar Saros 145: Total Solar Eclipse of 2252 Jan 12

• Solar Saros 146: Annular Solar Eclipse of 2280 Dec 22
