Thesolar eclipse of July 22, 2028, also called theGreat Australasian Eclipse by some media outlets,[1] is an upcoming totalsolar eclipse that will occur at the Moon'sdescending node of orbit on Saturday, July 22, 2028,[2] with amagnitude of 1.056. Asolar eclipse occurs when theMoon passes betweenEarth 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 1.8 days beforeperigee (on July 23, 2028, at 23:20 UTC), the Moon's apparent diameter will be larger.[3]
The central line of the path of the eclipse will cross the Australian continent from theKimberley region in the north-west and continue in a south-easterly direction throughWestern Australia, theNorthern Territory, south-westQueensland andNew South Wales, close to the towns ofWyndham,Kununurra,Tennant Creek,Birdsville,Bourke andDubbo, and continuing on through the centre ofSydney, where the eclipse will have a duration of over three minutes. It will also crossQueenstown andDunedin,New Zealand. Totality will also be viewable from two of Australia's external territories:Christmas Island and theCocos (Keeling) Islands. A partial eclipse will be visible for parts ofSoutheast Asia,Australia, andOceania.[citation needed]
This is the first timeSydney will experience a total solar eclipse since March 26, 1857 and will be the last until June 3, 2858.[4]

The path of the July 22, 2028 eclipse will be crossed by the paths of 3 more total solar eclipses within the following 10 years, including theNovember 2030,July 2037, andDecember 2038 total solar eclipses. The path of the July 2028 solar eclipse will intersect that of the November 2030 eclipse at a point betweenThargomindah andBourke inEastern Australia, that of the July 2037 eclipse nearBedourjie, in southwesternQueensland, and that of the December 2038 eclipse at a point in theTasman Sea, in between Australia and New Zealand.[6][7][8] This is similar to the intersection in the paths of theAugust 2017 andApril 2024 total solar eclipses in theUnited States, oversouthern Illinois, the intersection of theAugust 2027 andMarch 2034 total solar eclipses inEgypt, and the intersection of theAugust 1999 andMarch 2006 solar eclipses overTurkey; the intersections within these pairs of total eclipses occurred about 7 years apart.[9][10] This phenomenon is considered to be unusual, since the average interval for any given spot on Earth to observe a total solar eclipse is about once every 375 years. The intersection patterns are caused by the dynamics of theSaros cycle.[9]
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.

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.[11]
The partial solar eclipses onJune 12, 2029 andDecember 5, 2029 occur in the next lunar year eclipse set.

This eclipse is a part ofSaros 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 fromMay 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 oneexeligmos 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 onJune 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’sdescending node of orbit.[12]

Themetonic 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.

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.
