A partial solar eclipse occurred at the Moon's ascending node of orbit on Saturday, July 21, 1906,[1] with a magnitude of 0.3355. 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 partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.

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.[2]
The partial solar eclipses on February 23, 1906 and August 20, 1906 occur in the previous lunar year eclipse set.

Saros 115
This eclipse is a part of Saros series 115, repeating every 18 years, 11 days, and containing 72 events. The series started with a partial solar eclipse on June 21, 662 AD. It contains total eclipses from October 7, 842 AD through November 2, 1491; hybrid eclipses from November 12, 1509 through December 15, 1563; and annular eclipses from December 25, 1581 through May 27, 1816. The series ends at member 72 as a partial eclipse on August 12, 1942. 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 36 at 6 minutes, 24 seconds on July 5, 1293, and the longest duration of annularity was produced by member 65 at 1 minutes, 54 seconds on May 27, 1816. All eclipses in this series occur at the Moon’s ascending node of orbit.[3]

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.
