# Solar eclipse of February 7, 2073

A partial solar eclipse will occur at the Moon's descending node of orbit between Monday, February 6 and Tuesday, February 7, 2073, with a magnitude of 0.6768. 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.
The partial solar eclipse will be visible for parts of East Asia, Northeast Asia, and western Alaska.

## 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 February 2073 :
| February 7 Descending node (new moon) | February 22 Ascending node (full moon) |
| Partial solar eclipse Solar Saros 122 | Total lunar eclipse Lunar Saros 134 |

### Solar eclipses of 2073–2076

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 June 1, 2076 and November 26, 2076 occur in the next lunar year eclipse set.
Solar eclipse series sets from 2073 to 2076 :
| Descending node | Descending node | Descending node | Ascending node | Ascending node | Ascending node |
| Saros | Map | Gamma | Saros | Map | Gamma |
| 122 | February 7, 2073 Partial | 1.1651 | 127 | August 3, 2073 Total | −0.8763 |

### Saros 122

This eclipse is a part of Saros series 122, repeating every 18 years, 11 days, and containing 70 events. The series started with a partial solar eclipse on April 17, 991 AD. It contains total eclipses from July 12, 1135 through August 3, 1171; hybrid eclipses on August 13, 1189 and August 25, 1207; and annular eclipses from September 4, 1225 through October 10, 1874. The series ends at member 70 as a partial eclipse on May 17, 2235. 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 9 at 1 minutes, 25 seconds on July 12, 1135, and the longest duration of annularity was produced by member 50 at 6 minutes, 28 seconds on October 10, 1874. All eclipses in this series occur at the Moon’s descending node of orbit.
Series members 46–68 occur between 1801 and 2200: :
| 46 | 47 | 48 |
| August 28, 1802 | September 7, 1820 | September 18, 1838 |

### 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 July 3, 2065 and November 26, 2152 :
| July 3–4 | April 21–23 | February 7–8 | November 26–27 | September 13–15 |

### 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 2018 and 2200 :
| July 13, 2018 (Saros 117) | June 12, 2029 (Saros 118) | May 11, 2040 (Saros 119) | April 11, 2051 (Saros 120) | March 11, 2062 (Saros 121) |
| February 7, 2073 (Saros 122) | January 7, 2084 (Saros 123) | December 7, 2094 (Saros 124) | November 6, 2105 (Saros 125) | October 6, 2116 (Saros 126) |
| September 6, 2127 (Saros 127) | August 5, 2138 (Saros 128) | July 5, 2149 (Saros 129) | June 4, 2160 (Saros 130) | May 5, 2171 (Saros 131) |
| April 3, 2182 (Saros 132) | March 3, 2193 (Saros 133) |

### 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 :
| August 7, 1812 (Saros 113) | July 18, 1841 (Saros 114) | June 28, 1870 (Saros 115) |
