The Wednesday, Oct. 2, 2024, annular solar eclipse belongs to Saros series 144, which comprises 70 similar solar eclipses.

The Saros cycle, which spans approximately 6,585.3 days (18 years 11 days 8 hours), guides the periodicity and recurrence of solar eclipses. Each Saros series typically features a duration of 12 to 13 centuries and a composition of 70 or more eclipses.

Any two eclipses occupying the same Saros series via their separation by one Saros period exhibit a similar geometry. Their shared geometry of occurrence at the same lunar node assigns them to the same family, known as a series.

The two nodes in the lunar orbit around Earth indicate points of intersection with Earth's orbit. The descending node associates with the northward movement of each succeeding eclipse in the same descending node-occurring Saros series. The ascending node links with the southward movement of each subsequent eclipse in an ascending node-occurring Saros series.

All eclipses in solar Saros 144 series occur at the moon's descending node. According, each subsequent eclipse reveals northward movement by the moon. The southern hemisphere was the setting for the solar Saros 144 cycle's opening eclipse on Wednesday, April 11, 1736. The cycle's closing eclipse shifts to the northern hemisphere for its occurrence on Friday, May 5, 2980.

Solar Saros series 144 has a total duration of 1,244.08 years. The cycle traverses the 18th through 30th centuries.

Solar Saros series 144 comprises 70 solar eclipses. The cycle sequences through three sets that are ordered as eight partial solar eclipses, 39 annular solar eclipses and 23 partial solar eclipses.

With 39 occurrences, annular solar eclipses qualify as the most frequent eclipse type in solar Saros 144 series. The cycle's two partial sets, with eight eclipses in the first set and 23 in the second set, account for a combined total of 31 occurrences.

The partial solar eclipse on Wednesday, April 11, 1736, that opened the solar Saros 144 series numbered as the first of eight eclipses in the first of the cycle's two sets of partial solar eclipses and as first in the cycle's 70-member lineup. The April 1736 solar event continentally favored Antarctica's East Antarctica.

Annular solar eclipse of Wednesday, Oct. 2, 2024, numbers as the ninth of 39 eclipses in solar Saros 144 cycle's 39-member set of annular solar eclipses and as 17th in the cycle's 70-member lineup: "Permission is freely granted to reproduce this data when accompanied by an acknowledgment: Eclipse Predictions by Fred Espenak (NASA's GSFC)," via NASA Eclipse Web Site

The Wednesday, Oct. 2, 2024, annular solar eclipse appears in the second of solar Saros 144 cycle's three sets. The October 2024 solar event numbers as the ninth eclipse in the cycle's 39-member set of annular solar eclipses and as the 17th eclipse in solar Saros 144 cycle's 70-member lineup.

The October 2024 solar event begins as a partial solar eclipse and then incorporates an annular component. The October eclipse's path of annularity continentally favors South America via its traversal of the region of Patagonia in southern Chile (Republic of Chile; Spanish: República de Chile) and southern Argentina (Argentine Republic; Spanish: República Argentina). The contours of partiality expand the continental parameters to include Bolivia (Plurinational State of Bolivia; Spanish: Estado Plurinacional de Bolivia), Brazil (Federative Republic of Brazil; Portuguese: República Federativa do Brasil), Paraguay (Republic of Paraguay; Spanish: República del Paraguay; Guarani: Tavakuairetã Paraguái), Peru (Republic of Peru; Spanish: República del Perú; Aymara and Quechua: Piruw) and Uruguay (Oriental Republic of Uruguay; Spanish: República Oriental del Uruguay).

Annular solar eclipse of Wednesday, July 7, 1880, opened solar Saros 144 cycle's set of annular solar eclipses as the first of the set's 39 members and as ninth in the cycle's 70-member lineup: "Permission is freely granted to reproduce this data when accompanied by an acknowledgment: Eclipse Predictions by Fred Espenak (NASA's GSFC)," via NASA Eclipse Web Site

An annular solar eclipse on Wednesday, July 7, 1880, introduced solar Saros 144 cycle's 39-member set of annular solar eclipses. The July 1880 annular solar eclipse numbered as the first of the set's 39 eclipses and as the ninth eclipse in the cycle's 70-member lineup. The July 1880 solar event's path of annularity continentally favored South America via central Chile and southern Argentina. The parameters of the event's partial solar eclipse continentally favored South America and southern Africa. Partiality's visibility region added the South American countries of Bolivia, Brazil, Paraguay, Peru and Uruguay and also the African countries of Botswana (Republic of Botswana; Tswana: Lefatshe la Botswana), Lesotho (Kingdom of Lesotho; Sotho: Naha ea Lesotho), Namibia (Republic of Namibia) and South Africa (Republic of South Africa).

Annular solar eclipse of Friday, Sep. 22, 2006, which numbered as eighth in Saros 144 cycle's 39-member set of annular solar eclipses and as 16th in the cycle's 70-member lineup, was the immediate predecessor of the Wednesday, Oct. 2, 2024, annular solar eclipse: "Permission is freely granted to reproduce this data when accompanied by an acknowledgment: Eclipse Predictions by Fred Espenak (NASA's GSFC)," via NASA Eclipse Web Site

An annular solar eclipse on Friday, Sep. 22, 2006, was the immediate predecessor of the Wednesday, Oct. 2, 2024, annular solar eclipse in solar Saros 144 cycle's set of annular solar eclipses. The September 2006 solar event numbered as the set's eighth's eclipse and as the 16th eclipse in the 70-member cycle. The September 2006 solar event's path of annularity continentally favored northeastern South America via French Guiana (French: Guyane; Guianese Creole French: Lagwiyann), Guyana (Co-operative Republic of Guyana), Suriname (Republic of Suriname; Dutch: Republiek Suriname) and Venezuela (Bolivarian Republic of Venezuela; Spanish: República Bolivariana de Venezuela). The September 2006 solar event's partial solar eclipse continentally favored all of South America, parts of Antarctica's East Antarctica and West Antarctica and western and southern Africa.

Annular solar eclipse of Tuesday, Oct. 14, 2042, numbering as 10th of 39 eclipses in Saros 144 cycle's set of annular solar eclipses and as 18th in the cycle's 70-member lineup, is the cycle's immediate successor of the Monday, April 8, 2024, partial eclipse: "Permission is freely granted to reproduce this data when accompanied by an acknowledgment: Eclipse Predictions by Fred Espenak (NASA's GSFC)," via NASA Eclipse Web Site

A total solar eclipse on Tuesday, Oct. 14, 2042, sequences as solar Saros 144 cycle's immediate successor of the Wednesday, Oct. 2, 2024, annular solar eclipse. The October 2042 solar event numbers as the 10th eclipse in the cycle's 39-member annular set and as the 18th eclipse in solar Saros 144 cycle's 70-member lineup. The October 2042 path of annularity continentally favors Southeast Asia, via Malaysia and Thailand (Kingdom of Thailand: Thai: ราชอาณาจักรไทย, Ratcha-anachak Thai), and Australia. Annularity traverses Maritime Southeast Asia's islands of Borneo, Sulawesi, also known as Celebes, and Timor as well as Australasia's New Zealand (Maori: Aotearoa). The October 2042 solar event's partial solar eclipse stretches continentally to Antarctica and reaches across Southeast Asia to include East Asia.

A partial solar eclipse on Friday, May 5, 2980, closes solar Saros 144 cycle as the 23rd and last of the cycle's 23-member second set of partial solar eclipses and as the 70th and last of the cycle's 70-member lineup. The May 2980 partial solar eclipse continentally will favor north central Asia via transcontinental Russia (Russian Federation; Russian: Российская Федерация, Rossiiskaia Federatsiia).

Solar Saros series 144 posts a difference of 15 seconds between the cycle's longest and shortest annular solar eclipse, according to now-retired NASA (National Aeronautics and Space Administration) GSFC (Goddard Space Flight Center) astrophysicist Fred Espenak's eclipse predictions in "Extreme Durations and Magnitudes of Solar Eclipses of Saros 144" on the NASA Eclipse Web Site. The cycle's annular solar eclipse on Thursday, Dec. 29, 2168, will endure for 09 minutes 52 seconds. The Saros 144 cycle's longest annular solar eclipse numbers as the 17th eclipse in the cycle's 39-member annular set and as the 25th eclipse in the cycle's 70-member lineup. The solar Saros 144 cycle's shortest annular eclipse, which occurs Wednesday, Aug. 16, 2547, will last for only 00 minutes 37 seconds. The cycle's shortest annular eclipse sequences as the 38th eclipse in the cycle's 39-member annular set and as the 46th eclipse in the cycle's 70-member lineup.

Partial eclipse of Friday, May 5, 2980, closes Saros 144 cycle's second partial set as the set's 23rd and last eclipse and as the 70th and last eclipse in the cycle's 70-member lineup: "Permission is freely granted to reproduce this data when accompanied by an acknowledgment: Eclipse Predictions by Fred Espenak (NASA's GSFC)," via NASA Eclipse Web Site
