A totalsolar eclipse will occur at the Moon'sascending node of orbit between Monday, May 21 and Tuesday, May 22, 2096,[1] with amagnitude of 1.0737. Asolar eclipse occurs when theMoon passes between Earth and theSun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon'sapparent 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 13 hours afterperigee (on May 21, 2096, at 12:30 UTC), the Moon's apparent diameter will be larger.[2]
The path of totality will be visible from parts ofIndonesia and thePhilippines. Totality will end approximately 1000 miles (1600 km) off the United StatesWest Coast. A partial solar eclipse will also be visible for parts ofSoutheast Asia,East Asia, northernAustralia,Hawaii, and northwesternNorth America.
Overall, at 6 minutes and 7 seconds, this will be the third longest total solar eclipse of the 21st century. The only two longer eclipses in the century areJuly 22, 2009 andAugust 2, 2027. The longest duration of this eclipse on land will be seen inSurigao del Sur,the Philippines, 4 minutes and 38 seconds.
This will be the first eclipse ofsaros series 139 to exceedseries 136 in length of totality. The length of totality for saros 139 is increasing, while that of Saros 136 is decreasing.

This eclipse is part of aneclipse 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 afortnight. The first and last eclipse in this sequence is separated by onesynodic month.

This eclipse is a member of asemester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternatingnodes of the Moon's orbit.[4]
The solar eclipses onJanuary 16, 2094 (total) andJuly 12, 2094 (partial) occur in the previous lunar year eclipse set, and the partial solar eclipses onApril 1, 2098 andSeptember 25, 2098 occur in the next lunar year eclipse set.

This eclipse is a part ofSaros series 139, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on May 17, 1501. It contains hybrid eclipses from August 11, 1627 through December 9, 1825 and total eclipses from December 21, 1843 through March 26, 2601. There are no annular eclipses in this set. The series ends at member 71 as a partial eclipse on July 3, 2763. Its eclipses are tabulated in three columns; every third eclipse in the same column is oneexeligmos apart, so they all cast shadows over approximately the same parts of the Earth.
The longest duration of totality will be produced by member 61 at 7 minutes, 29.22 seconds onJuly 16, 2186. This date is the longest solar eclipse computed between 4000 BC and AD 6000.[5] All eclipses in this series occur at the Moon’sascending node of orbit.[6]

This eclipse is a part of atritos cycle, repeating at alternating nodes every 135synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with theanomalistic 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.

This eclipse is a part of the long periodinex cycle, repeating at alternating nodes, every 358synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with theanomalistic 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.
