The Tuesday, Nov. 13, 2012, total solar eclipse belongs to Saros cycle 133, which comprises 72 solar eclipses with similar geometries.

November’s total solar eclipse begins Tuesday, Nov. 13, 2012, at 19:37:58.1 Universal Time, according to the NASA Eclipse Web Site. Greatest eclipse takes place at 22:11:48.2 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 Wednesday, Nov. 14, at 00:45:34.1 UT.

November 2012’s total solar eclipse numbers as 45 in the lineup of 72 solar eclipses that compose Saros cycle 133. Similar geometries connect the 72 solar eclipses as a family, known as a series.

The NASA Eclipse Web Site describes Saros 133 solar eclipses as sharing the geometry of occurring at the moon’s ascending node. With each succeeding eclipse in Saros 133, the lunar movement is southward of the ascending node.

A pair of ascending and descending nodes designates the intersections of Earth’s orbit by the moon’s orbit. The two nodes evince the approximately 5.1 degree tilt of the moon’s orbit with respect to Earth’s orbit. The ascending node relates to the lunar orbital crossing to the north of Earth’s orbit. The descending node identifies 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) rules the periodicity and recurrence of solar eclipses. Each Saros series contains 70 or more eclipses and occurs over 12 to 13 centuries.

Saros solar series 133 lasts for 1,280.14 years, according to the NASA Eclipse Web Site. The series lasts for 13 centuries. Saros solar series 133 spans the 13th through 25th centuries.

Solar eclipses in Saros series 133 display a sequence order of 12 partial solar eclipses, six annular solar eclipses, one hybrid solar eclipse, 46 total solar eclipses and seven partial solar eclipses. Total solar eclipses rate as the most number of eclipses to Saros series 133, with a total of 46 occurrences. Partial solar eclipses are the second most frequent, with a total of 19 occurrences.

The partial solar eclipse of July 13, 1219, opened Saros solar series 133. This Northern Hemisphere event reached greatest eclipse, with coordinates of 68.4 north at 137.2 west, over the northwestern corner of present-day Yukon Territory in western Canada.

The partial solar eclipse of Saturday, Sept. 5, 2499, will close Saros solar series 133. This Southern Hemisphere event’s greatest eclipse, with coordinates of 71.9 south at 144.2 east, will favor East Antarctica, between the Davis Sea and the Ross Sea.

The total solar eclipse of Tuesday, Nov. 13, 2012, numbers as 26 in Saros solar series 133’s sequence of 46 total solar eclipses. This event’s greatest eclipse, with coordinates of 40.0 south at 161.3 west, will take place over the southwestern Pacific Ocean, east of New Zealand.

A total solar eclipse on Nov. 3, 1994, was the immediate predecessor of the November 2012 total solar eclipse in Saros solar series 133. This event’s greatest eclipse, with coordinates of 35.4 south at 34.2 west, occurred over Fulton County, northwestern Ohio, in the Midwestern United States.

The May 1994 annular solar eclipse took place as number 25 in Saros solar series 128’s sequence of 32 annular solar eclipses. This eclipse numbered 44 in the series’ lineup of 72 solar eclipses.

A partial solar eclipse on Monday, Nov. 25, 2030, succeeds the May 2012 annular solar eclipse in Saros solar series 133. This event will stage its greatest eclipse, with coordinates of 43.6 south at 71.2 east, over the southern Indian Ocean, southwest of Île Amsterdam and northeast of the French Southern and Antarctic Lands.

The November 2030 solar eclipse will occur as number 27 in Saros solar series 133’s sequence of 46 total solar eclipses. This eclipse numbers 46 in the series’ lineup of 72 solar eclipses.

The takeaway for the Tuesday, Nov. 13, 2012, total solar eclipse is that the astronomical event numbers as 45 in Saros solar series 133’s lineup of 72 solar eclipses and as 26 within the series’ sequence of 46 total solar eclipses.
