A total solar eclipse will occur at the Moon's descending node of orbit on Monday, August 2, 2027,[1] with a magnitude of 1.079. 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 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 before perigee (on August 2, 2027, at 7:25 UTC), the Moon's apparent diameter will be larger.[2]
Path
[edit]Totality will commence over the eastern Atlantic Ocean and travel across the Strait of Gibraltar between Spain and Morocco, and continue across parts of North Africa and the Middle East. Major cities and locations under the path of totality will include:[3]
- Cadiz and Malaga, in southern Spain
- Gibraltar
- Tangier, Morocco
- Oran, Algeria
- Sfax, Tunisia
- Benghazi, Libya
- Luxor in central Egypt
- Jeddah and Mecca in southwest Saudi Arabia
- Sana'a in western Yemen
- The tip of the Horn of Africa in extreme northeast Somalia
- Islands in the British Indian Ocean Territory
The maximum duration of totality will be observed in Egypt, approximately 37 miles (60 km) southeast of Luxor, and will last 6 minutes and 22 seconds.[4]
A partial solar eclipse will be visible from the extreme east tip of Maine, United States, far eastern Quebec and the Atlantic Provinces in Canada, southern Greenland, Iceland, Ireland, Great Britain, nearly the entirety of the European continent, all but the southern quarter of Africa, the Middle East, and from South and Southeast Asia.[3]
It will be the first of three total solar eclipses that are observable in Tunisia 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, after August 2026. An annular eclipse will appear in Spain in January 2028. A national eclipse committee has been established to coordinate eclipse-related activities.[6]
Duration
[edit]This is the second longest total solar eclipse in the 21st century, the longest being the eclipse prior to this one in Solar 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, uninhabited North Iwo Jima.[7] The maximum duration of this eclipse is 6 minutes and 23.2 seconds, occurring in the northeastern part of Egypt's New Valley Governorate. The location of the greatest eclipse is about 250 kilometres (160 mi) southeast in Red 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 until June 3, 2114.[8]

Bright stars and planets visible during totality
[edit]The eclipsed Sun will be in mid-Cancer, a few degrees southeast of the Beehive Cluster (which will not be visible to the naked eye) and Venus (which will most definitely be seen if the sky is at all transparent). Mercury will be several degrees west of Venus and lined up with Pollux and Castor. Saturn will be many degrees west of the Sun. Jupiter and Regulus will be close together in Leo about 20 degrees east of the Sun, and Mars will be many degrees farther east in Virgo. Over most of the continental areas in the path of totality, the Winter Hexagon will be visible, although on the Arabian Peninsula its westernmost stars -- Aldebaran and Rigel -- will be low. In the British Indian Ocean Territory the Winter Hexagon stars will either have disappeared below the western horizon or will be very low, but Alpha Centauri, Beta Centauri and the Southern Cross will be well up in the south.
Eclipse season
[edit]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. The first and last eclipse in this sequence is separated by one synodic month.

Solar eclipses of 2026–2029
[edit]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.[10]
The partial solar eclipses on June 12, 2029 and December 5, 2029 occur in the next lunar year eclipse set.

Saros 136
[edit]This eclipse is a part of Saros 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 one exeligmos 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 on June 20, 1955. All eclipses in this series occur at the Moon’s descending node of orbit.[11]

Metonic series
[edit]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.

Tritos series
[edit]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.

[edit]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.
