# Solar eclipse of August 30, 1924

A partial solar eclipse occurred at the Moon's ascending node of orbit on Saturday, August 30, 1924, with a magnitude of 0.4245. 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.
A partial eclipse was visible for parts of Greenland, the Russian SFSR, and Northeast Asia.

## 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. The first and last eclipse in this sequence is separated by one synodic month.
Eclipse season of July–August 1924 :
| July 31 Ascending node (new moon) | August 14 Descending node (full moon) | August 30 Ascending node (new moon) |
| Partial solar eclipse Solar Saros 115 | Total lunar eclipse Lunar Saros 127 | Partial solar eclipse Solar Saros 153 |

### Solar eclipses of 1921–1924

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 July 31, 1924 occurs in the next lunar year eclipse set.
Solar eclipse series sets from 1921 to 1924 :
| Descending node | Descending node | Descending node | Ascending node | Ascending node | Ascending node |
| Saros | Map | Gamma | Saros | Map | Gamma |
| 118 | April 8, 1921 Annular | 0.8869 | 123 | October 1, 1921 Total | −0.9383 |

### Saros 153

This eclipse is a part of Saros series 153, repeating every 18 years, 11 days, and containing 70 events. The series started with a partial solar eclipse on July 28, 1870. It contains annular eclipses from December 17, 2104 through May 26, 2970. There are no hybrid or total eclipses in this set. The series ends at member 70 as a partial eclipse on August 22, 3114. 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 will be produced by member 38 at 7 minutes, 1 seconds on September 5, 2537. All eclipses in this series occur at the Moon’s ascending node of orbit.
Series members 1–19 occur between 1870 and 2200: :
| 1 | 2 | 3 |
| July 28, 1870 | August 7, 1888 | August 20, 1906 |

### 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 April 5, 1837 and June 17, 1928 :
| April 5–6 | January 22–23 | November 10–11 | August 28–30 | June 17–18 |

### 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 1946 :
| August 5, 1804 (Saros 142) | July 6, 1815 (Saros 143) | June 5, 1826 (Saros 144) | May 4, 1837 (Saros 145) | April 3, 1848 (Saros 146) |
| March 4, 1859 (Saros 147) | January 31, 1870 (Saros 148) | December 31, 1880 (Saros 149) | December 1, 1891 (Saros 150) | October 31, 1902 (Saros 151) |
| September 30, 1913 (Saros 152) | August 30, 1924 (Saros 153) | July 30, 1935 (Saros 154) | June 29, 1946 (Saros 155) |

### 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 2069 :
| November 18, 1808 (Saros 149) | October 29, 1837 (Saros 150) | October 8, 1866 (Saros 151) |
| September 18, 1895 (Saros 152) | August 30, 1924 (Saros 153) | August 9, 1953 (Saros 154) |
