# Solar eclipse of September 3, 2081

A total solar eclipse will occur at the Moon's descending node of orbit on Wednesday, September 3, 2081, with a magnitude of 1.072. 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. Occurring about 5 hours before perigee (on September 3, 2081, at 14:05 UTC), the Moon's apparent diameter will be larger.
The path of totality will be visible from parts of France, Germany, Switzerland, Liechtenstein, Austria, Italy, Slovenia, Croatia, Hungary, Bosnia and Herzegovina, Serbia, Romania, Bulgaria, Turkey, Syria, Iraq, Kuwait, far western Iran, Bahrain, Qatar, the United Arab Emirates, eastern Saudi Arabia, Oman, the Maldives, and southern Indonesia. A partial solar eclipse will also be visible for parts of Greenland, Europe, North Africa, Northeast Africa, the Middle East, Central Asia, South Asia, and Southeast 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.
Eclipse season of September 2081 :
| September 3 Descending node (new moon) | September 18 Ascending node (full moon) |
| Total solar eclipse Solar Saros 136 | Penumbral lunar eclipse Lunar Saros 148 |

### Solar eclipses of 2080–2083

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 15, 2083 occurs in the next lunar year eclipse set.
Solar eclipse series sets from 2080 to 2083 :
| Ascending node | Ascending node | Ascending node | Descending node | Descending node | Descending node |
| Saros | Map | Gamma | Saros | Map | Gamma |
| 121 | March 21, 2080 Partial | −1.0578 | 126 | September 13, 2080 Partial | 1.0723 |

### Saros 136

This eclipse is a part of Saros series 136, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on June 14, 1360. It contains annular eclipses from September 8, 1504 through November 12, 1594; hybrid eclipses from November 22, 1612 through January 17, 1703; and total eclipses from January 27, 1721 through May 13, 2496. The series ends at member 71 as a partial eclipse on July 30, 2622. 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 was produced by member 9 at 32 seconds on September 8, 1504, and the longest duration of totality was produced by member 34 at 7 minutes, 7.74 seconds on June 20, 1955. All eclipses in this series occur at the Moon’s descending node of orbit.

### 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 2200 :
| October 19, 1808 (Saros 111) | September 19, 1819 (Saros 112) | August 18, 1830 (Saros 113) | July 18, 1841 (Saros 114) | June 17, 1852 (Saros 115) |

### 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.
