# Solar eclipse of August 9, 1953

A partial solar eclipse occurred at the Moon's descending node of orbit on Sunday, August 9, 1953, with a magnitude of 0.3729. 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 Antarctica and extreme southern South America.

## 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 July–August 1953 :
| July 11 Descending node (new moon) | July 26 Ascending node (full moon) | August 9 Descending node (new moon) |
| Partial solar eclipse Solar Saros 116 | Total lunar eclipse Lunar Saros 128 | Partial solar eclipse Solar Saros 154 |

### Solar eclipses of 1950–1953

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 11, 1953 occurs in the next lunar year eclipse set.
Solar eclipse series sets from 1950 to 1953 :
| Ascending node | Ascending node | Ascending node | Descending node | Descending node | Descending node |
| Saros | Map | Gamma | Saros | Map | Gamma |
| 119 | March 18, 1950 Annular (non-central) | 0.9988 | 124 | September 12, 1950 Total | 0.8903 |

### Saros 154

This eclipse is a part of Saros series 154, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on July 19, 1917. It contains annular eclipses from October 3, 2043 through March 27, 2332; hybrid eclipses from April 7, 2350 through April 29, 2386; and total eclipses from May 9, 2404 through May 29, 3035. The series ends at member 71 as a partial eclipse on August 25, 3179. 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 9 at 3 minutes, 41 seconds on October 13, 2061, and the longest duration of totality will be produced by member 35 at 4 minutes, 50 seconds on July 25, 2530. All eclipses in this series occur at the Moon’s descending node of orbit.
Series members 1–16 occur between 1917 and 2200: :
| 1 | 2 | 3 |
| July 19, 1917 | July 30, 1935 | August 9, 1953 |

### 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 :

### 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 1964 :
| September 17, 1811 (Saros 141) | August 16, 1822 (Saros 142) | July 17, 1833 (Saros 143) | June 16, 1844 (Saros 144) | May 16, 1855 (Saros 145) |
| April 15, 1866 (Saros 146) | March 15, 1877 (Saros 147) | February 11, 1888 (Saros 148) | January 11, 1899 (Saros 149) | December 12, 1909 (Saros 150) |
| November 10, 1920 (Saros 151) | October 11, 1931 (Saros 152) | September 10, 1942 (Saros 153) | August 9, 1953 (Saros 154) | July 9, 1964 (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) |
