A total solar eclipse occurred at the Moon's descending node of orbit between Tuesday, March 8 and Wednesday, March 9, 2016,[1][2][3][4][5] with a magnitude of 1.045. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's and the apparent path of the Sun and Moon intersect, blocking all direct sunlight and turning daylight into darkness; the Sun appears to be black with a halo around it. 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 1.25 days before perigee (on March 10, 2016, at 7:00 UTC), the Moon's apparent diameter was larger.[6]
The eclipse was clearly visible in many parts of Indonesia, including Central Sulawesi and Ternate, but obscured by clouds and smokes in Palembang, the largest city on the path of totality.[8][9] The eclipse coincided with Nyepi, a public holiday in Indonesia and the end of the Balinese saka calendar. Because Nyepi is normally a day of silence, Muslims in Bali had to be given special dispensation to attend special prayer services during the eclipse.[10]
Path of the eclipse
On March 9, 2016, a large area of the Pacific, covering Indonesia, Borneo, but also large parts of Southeast Asia and Australia, witnessed a partial solar eclipse. It was total in multiple islands of Indonesia, three atolls of the Federated States of Micronesia (Eauripik, Woleai and Ifalik) and the central Pacific, starting at sunrise over Sumatra and ending at sunset north of Hawaii. In the Eastern Pacific Ocean, the totality exceeded a duration of more than 4 minutes.[11]
ed, and much of East Asia witnessed more than 50% partial eclipse.[11][12]
The largest city along the path of totality was Palembang in southern Sumatra (423 km (263 mi) from Jakarta and 478 km (297 mi) from Singapore).[9]
In order to watch the total solar eclipse, Alaska Airlines adjusted the flight plan for Flight 870. The flight passed through the umbral shadow about 695 miles (1,118 km) north of Hawaii.[13]

Shown below are two tables displaying details about this particular solar eclipse. The first table outlines times at which the moon's penumbra or umbra attains the specific parameter, and the second table describes various other parameters pertaining to this eclipse.[14]
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.
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.[15]
The partial solar eclipse on July 13, 2018 occurs in the next lunar year eclipse set.
This eclipse is a part of Saros series 130, repeating every 18 years, 11 days, and containing 73 events. The series started with a partial solar eclipse on August 20, 1096. It contains total eclipses from April 5, 1475 through July 18, 2232. There are no annular or hybrid eclipses in this set. The series ends at member 73 as a partial eclipse on October 25, 2394. 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 30 at 6 minutes, 41 seconds on July 11, 1619. All eclipses in this series occur at the Moon’s descending node of orbit.[16]
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.
21 eclipse events between May 21, 1993 and May 20, 2069
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.
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.
