A totalsolar eclipse will occur at the Moon'sdescending node of orbit on Monday, August 2, 2027,^[1] with amagnitude of 1.079. 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 2.5 hours beforeperigee (on August 2, 2027, at 7:25 UTC), the Moon's apparent diameter will be larger.^[2]

Totality will commence over the easternAtlantic Ocean and travel across theStrait of Gibraltar betweenSpain andMorocco, and continue across parts ofNorth Africa and theMiddle East. Also, It will be visible inCentral Asia,Indian Ocean Islands. Major cities and locations under the path of totality will include:^[3]

• Cadiz andMálaga, in southernSpain
• Gibraltar
• Tangier,Morocco
• Oran,Algeria
• Sfax,Tunisia
• Benghazi,Libya
• Luxor in centralEgypt
• Jeddah andMecca in southwestSaudi Arabia
• Sana'a in westernYemen
• The tip of theHorn of Africa in extreme northeastSomalia
• Islands in theBritish Indian Ocean Territory

The maximum duration of totality will be observed inEgypt, approximately 37 miles (60 km) southeast ofLuxor, and will last 6 minutes and 22 seconds.^[4]

A partial solar eclipse will be visible from the extreme east tip ofMaine,United States, far easternQuebec and theAtlantic Provinces inCanada, southernGreenland,Iceland,Ireland,Great Britain, nearly the entirety of theEuropean continent, all but the southern quarter ofAfrica, theMiddle East, and fromSouth andSoutheast Asia.^[3]

It will be the first of three total solar eclipses that are observable inTunisia in the 21st century, passing over the central part of the country.^[5] It will be the second total eclipse in Spain within a year, afterAugust 2026. An annular eclipse will appear in Spain inJanuary 2028. A national eclipse committee has been established to coordinate eclipse-related activities.^[6]

This is the second longest total solar eclipse in the 21st century, the longest being the eclipse prior to this one inSolar Saros 136,that of July 22, 2009. The 2009 eclipse maximum duration of 6 minutes and 39.5 seconds occurred on the Pacific Ocean, and the longest duration on land was on remote, uninhabitedNorth Iwo Jima where visiting is not allowed without special permission.^[7] The maximum duration of this eclipse is 6 minutes and 23.2 seconds, occurring in the northeastern part of Egypt'sNew Valley Governorate. The location of the greatest eclipse is about 250 kilometres (160 mi) southeast inRed Sea Governorate, with a slightly shorter duration. This is the longest total solar eclipse on easily accessible land in the 21st century; a longer one will not occur untilJune 3, 2114.^[8]

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.^[9]

The eclipsed Sun will be in mid-Cancer, a few degrees southeast of theBeehive Cluster (which will not be visible to the naked eye) andVenus (which will most definitely be seen if the sky is at all transparent).Mercury will be several degrees west of Venus. Venus will be hanging out with Jupiter in the (constellation) Gemini home ofPollux andCastor.Saturn will be many degrees west of the Sun.Mars will be many degrees farther east inVirgo. Over most of the continental areas in the path of totality, theWinter Hexagon will be visible, although on theArabian Peninsula its westernmost stars --Aldebaran andRigel—will be low. In theBritish Indian Ocean Territory theWinter Hexagon stars will either have disappeared below the western horizon or will be very low, butAlpha Centauri,Beta Centauri and theSouthern Cross will be well up in the south.

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 a fortnight. 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.^[10]

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 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 oneexeligmos 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 onJune 20, 1955. All eclipses in this series occur at the Moon’sdescending node of orbit.^[11]

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.
