# Solar eclipse of August 2, 2046

A total solar eclipse will occur at the Moon's descending node of orbit on Thursday, August 2, 2046, with a magnitude of 1.0531. 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 greater than the Sun's, blocking all direct sunlight. 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 2 days before perigee (on August 4, 2046, at 10:20 UTC), the Moon's apparent diameter will be larger.
The path of totality will be visible from parts of eastern Brazil, Angola, the panhandle of Namibia, Botswana, South Africa, Eswatini, extreme southern Mozambique, and the Kerguelen Islands. A partial solar eclipse will also be visible for parts of eastern South America, Africa, and East Antarctica.

## 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 2046 :
| July 18 Ascending node (full moon) | August 2 Descending node (new moon) |
| Partial lunar eclipse Lunar Saros 120 | Total solar eclipse Solar Saros 146 |

### Solar eclipses of 2044–2047

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 23, 2047 and December 16, 2047 occur in the next lunar year eclipse set.
Solar eclipse series sets from 2044 to 2047 :
| Ascending node | Ascending node | Ascending node | Descending node | Descending node | Descending node |
| Saros | Map | Gamma | Saros | Map | Gamma |
| 121 | February 28, 2044 Annular | −0.9954 | 126 | August 23, 2044 Total | 0.9613 |

### Saros 146

This eclipse is a part of Saros series 146, repeating every 18 years, 11 days, and containing 76 events. The series started with a partial solar eclipse on September 19, 1541. It contains total eclipses from May 29, 1938 through October 7, 2154; hybrid eclipses from October 17, 2172 through November 20, 2226; and annular eclipses from November 30, 2244 through August 10, 2659. The series ends at member 76 as a partial eclipse on December 29, 2893. 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 26 at 5 minutes, 21 seconds on June 30, 1992, and the longest duration of annularity will be produced by member 63 at 3 minutes, 30 seconds on August 10, 2659. 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 :
| June 16, 1806 (Saros 124) | May 16, 1817 (Saros 125) | April 14, 1828 (Saros 126) | March 15, 1839 (Saros 127) | February 12, 1850 (Saros 128) |

### 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 :
