The Wednesday, Nov. 28, 2012, penumbral lunar eclipse belongs to Saros cycle 145, which comprises 71 lunar eclipses with similar geometries.

November’s penumbral lunar eclipse begins Wednesday, Nov. 28, at 12:14:58 Universal Time, according to NASA’s Eclipse Web Site. Greatest eclipse takes place at 14:33:00 UT. Greatest eclipse indicates the instant of the moon’s closest passage to the axis of Earth’s shadow. The eclipse ends at 16:51:02 UT.

November 2012’s penumbral lunar eclipse appears as number 11 in the lineup of 71 lunar eclipses that compose Saros cycle 145. Similar geometries group the 71 lunar eclipses into a family, known as a series.

Retired NASA astrophysicist Fred Espenak’s EclipseWise website describes Saros 145 lunar eclipses as sharing the geometry of occurring at the moon’s descending node. With each succeeding eclipse in Saros 145, the lunar movement is northward with respect to the descending node.

The ascending node and a descending node pair as markers of the intersections of Earth’s orbit by the moon’s orbit. The two nodes relate to the approximately 5.1 degree tilt of the lunar orbit with respect to Earth’s orbit. The ascending node concerns the moon’s orbital crossing to the north of Earth’s orbit. The descending node corresponds with the lunar orbital crossing to the south of Earth’s orbit.

A Saros cycle of approximately 6,585.3 days (18 years 11 days 8 hours establishes the periodicity and recurrence of eclipses. A Saros series contains 70 or more lunar eclipses, with each separated from its predecessor by a Saros cycle. A Saros series typically encompasses 12 to 15 centuries.

Saros series 145 lasts for 1,262.11 years, according to NASA Eclipse Web Site. Saros series 145 continues for 13 centuries. Saros series 145 spans the 19th through 31st centuries.

Lunar eclipses in Saros cycle 145 sequence as 18 penumbral lunar eclipses, 10 partial lunar eclipses, 15 total lunar eclipses, 20 partial lunar eclipses and eight penumbral lunar eclipses. Partial lunar eclipses occur with the most frequency in Saros series 145, with a total of 30 occurrences. Penumbral lunar eclipses appear as the second most frequent lunar eclipse type in the series, with a total of 26 occurrences.

The 19th century’s penumbral eclipse of Saturday, Aug. 11, 1832, initiated Saros series 145. This eclipse occurred near the southern edge of the penumbra (shadow’s lighter, outer region). This event staged its greatest eclipse over the South Pacific’s marginal Coral Sea, east of Queensland’s Cape York Peninsula.

The 31st century’s penumbral eclipse of Sunday, Sept. 16, 3094, ends Saros series 145. This eclipse will occur near the penumbra’s northern edge.

The Wednesday, Nov. 28, 2012, penumbral lunar eclipse occurs as number 11 within the opening sequence of 18 penumbral lunar eclipses in Saros series 145. This event will experience its greatest eclipse over the North Pacific Ocean, northwest of the U.S. Territory of Guam and southwest of the Japanese island of Iwo Jima.

The penumbral lunar eclipse of Friday, Nov. 18, 1994, is the immediate predecessor of November 2012’s penumbral lunar eclipse. This event’s greatest eclipse took place over northeastern Pacific Ocean, west of Mexico’s state of Michoacán.

The November 1994, penumbral lunar eclipse appears as number 10 within the opening sequence of 18 penumbral lunar eclipses in Saros series 145. This eclipse occurs as number 10 in the series’ lineup of 71 lunar eclipses.

The penumbral lunar eclipse of Monday, Dec. 9, 2030, is the successor of the Wednesday, Nov. 28, 2012, penumbral lunar eclipse in Saros series 145. This event’s greatest eclipse will take place over southeastern Libya’s Kufra District.

The December 2030 eclipse occurs as number 12 within the opening sequence of 18 penumbral lunar eclipses in Saros series 145. This eclipse appears as number 12 in the series’ lineup of 71 lunar eclipses.

The takeaway for the Wednesday, Nov. 28, 2012, penumbral lunar eclipse is that the astronomical event occurs as number 11 in Saros series 145’s lineup of 71 lunar eclipses and as number 11 in the series’ opening sequence of 18 penumbral lunar eclipses.
