The Sunday, Nov. 3, 2013, hybrid solar eclipse belongs to Saros cycle 143, which comprises 72 solar eclipses with similar geometries.

November’s hybrid solar eclipse begins Sunday, Nov. 3, 2013, at 10:04:33.8 Universal Time, according to the NASA Eclipse Web Site. Greatest eclipse takes place at 12:46:28.6 UT. Greatest eclipse refers to the instant of the closest passage of the lunar shadow cone’s axis to Earth’s center. The eclipse ends at 15:28:21.7 UT.

November 2013’s hybrid solar eclipse numbers as 23 in the lineup of 72 solar eclipses that compose Saros cycle 143. Similar geometries bring together the series’ 72 solar eclipses into a family, known as a series.

The NASA Eclipse Web Site describes Saros 143 solar eclipses as sharing the geometry of occurring at the moon’s ascending node. With each succeeding eclipse in Saros 143, the lunar movement is southward of the ascending node.

A pair of ascending and descending nodes signifies the intersections of Earth’s orbit by the moon’s orbit. The two nodes express the approximately 5.1 degree tilt of the moon’s orbit with respect to Earth’s orbit. The ascending node links with the lunar orbital crossing to the north of Earth’s orbit. The descending node concerns the lunar orbital crossing to the south of Earth’s orbit.

The Saros cycle of approximately 6,585.3 days (18 years 11 days 8 hours) guides the periodicity and recurrence of solar eclipses. Each Saros series comprises 70 or more eclipses and endures for 12 to 13 centuries.

Saros solar series 143 lasts for 1,280.14 years, according to the NASA Eclipse Web Site. The series lasts for 13 centuries. Saros solar series 143 spans the 17th through 29th centuries.

Solar eclipses in Saros series 143 follow a sequence order of 10 partial solar eclipses, 12 total solar eclipses, four hybrid solar eclipses, 26 annular solar eclipses and 20 partial solar eclipses. Partial solar eclipses occur as the most frequent eclipse type in Saros series 143, with a total of 30 occurrences. Annular solar eclipses claim the secondmost frequency, with a total of 26 occurrences.

The partial solar eclipse of Friday, March 7, 1617, opened Saros solar series 143. This Northern Hemisphere event’s greatest eclipse, with coordinates of 61.2 north at 48.6 west, took place over Greenland’s southwestern coast.

The partial solar eclipse of Tuesday, April 23, 2897, will close Saros solar series 143. This Southern Hemisphere event’s greatest eclipse, with coordinates of 61.9 south at 141.2 west, will occur over the southwestern Pacific Ocean, near the Pacific’s overlap with the Southern Ocean.

The hybrid solar eclipse of Sunday, Nov. 3, 2013, numbers as first in Saros solar series 143’s sequence of four hybrid solar eclipses. This event experiences its greatest eclipse, with coordinates of 3.5 north at 11.7 west, 3.5 degrees north of the equator, in the northeastern Atlantic Ocean.

A total solar eclipse on Tuesday, Oct. 24, 1995, was the immediate predecessor of the November 2013 hybrid solar eclipse in Saros solar series 143. This event’s greatest eclipse, with coordinates of 8.4 north at 113.2 east, occurred over the Spratly Islands in the South China Sea.

The October 1995 total solar eclipse closed Saros solar series 143’s first string of 12 total solar eclipses. This eclipse numbered 22 in the series’ lineup of 72 solar eclipses.

A hybrid solar eclipse on Tuesday, Nov. 14, 2031, succeeds the November 2013 hybrid solar eclipse in Saros solar series 138. This event will stage its greatest eclipse, with coordinates of 0.6 south at 137.6 west, over the open South Pacific Ocean, less than one degree south of the equator.

The November 2031 solar eclipse will occur as the second in Saros solar series 143’s sequence of four hybrid solar eclipses. This eclipse numbers 24 in the series’ lineup of 72 solar eclipses.

The takeaway for the Sunday, Nov. 3, 2013, hybrid solar eclipse is that the astronomical event numbers as 23 in Saros solar series 143’s lineup of 72 solar eclipses and opens the series’ sequence of four hybrid solar eclipses.
