The Monday, Nov. 30, penumbral lunar eclipse belongs to Saros series 116, a family of 73 lunar eclipses with similar geometries.

November’s penumbral lunar eclipse begins Monday, Nov. 30, at 07:32:21 Universal Time (2:32 a.m. Eastern Standard Time), according to NASA’s Eclipse Web Site. Greatest eclipse, which signifies the instant of the moon’s closest passage to the axis of Earth’s shadow, happens at 09:42:49.0 UT (4:42 a.m. EST). The eclipse ends at 11:53:20 (6:53 a.m. EST).

November’s penumbral lunar eclipse appears as number 58 in the lineup of 73 lunar eclipses in Saros series 116. Similar geometries group the 73 lunar eclipses into a family, known as a series.

Saros 116 lunar eclipses have the shared geometry of occurrences at the moon’s ascending node. With each subsequent eclipse, the lunar movement in Saros series 116 is southward with respect to the node.

A pair of nodes represent the intersections of Earth’s orbit with the lunar orbit. The two nodes pertain to the approximately 5.1 degree tilt of the lunar orbit with respect to Earth’s orbit. The ascending node associates with the lunar orbital crossing to the north of Earth’s orbit. The descending node links with the moon’s orbital crossing to the south of Earth’s orbit.

The Saros cycle, which approximates 6,585.3 days (18 years 11 days 8 hours), guides the periodicity and recurrence of eclipses. A Saros series contains 70 or more lunar eclipses. A Saros cycle separates each eclipse within a particular Saros series. A Saros series typically spans 12 to 15 centuries.

Saros series 116 has a duration of 1,298.17 years. Saros series 116 unfolds over 14 centuries, beginning in the 10th century and ending in the 23rd century.

The 73 lunar eclipses in Saros series 116 observe an order of nine penumbral lunar eclipses, nine partial lunar eclipses, 27 total lunar eclipses, eight partial lunar eclipses and 20 penumbral lunar eclipses. Penumbral lunar eclipses number as the most frequent eclipse type in Saros series 116, with a total of 29 occurrences. Total lunar eclipses are the second most frequent eclipse type, with 27 occurrences.

The 10th century’s penumbral eclipse of Saturday, March 11, 0993, opened Saros series 116. This eclipse occurred near the northern edge of the penumbra, the shadow’s lighter, outer region. This event staged its greatest eclipse over the Gulf of Guinea, west of the west Central African Republic of Equatorial Guinea’s Bioko Island, in the Northern Hemisphere.

The 23rd century’s penumbral eclipse of Thursday, May 14, 2291, ends Saros series 116. This eclipse will occur near the penumbra’s southern edge. This event’s greatest eclipse will take place over southeastern Bolivia’s Cordillera Province, in the Southern Hemisphere.

The Monday, Nov. 30, 2020, penumbral lunar eclipse occurs as number 58 within the lineup of 73 lunar eclipses in Saros series 116.  November’s penumbral lunar eclipse numbers as fifth in the closing sequence of 20 penumbral lunar eclipses in Saros series 116. This event will experience its greatest eclipse over the open waters of the North Pacific Ocean, east of the Hawaiian island of Maui, in the Northern Hemisphere.

The penumbral lunar eclipse of Wednesday, Nov. 20, 2002, is the immediate predecessor of November’s penumbral lunar eclipse in Saros series 116. This event’s greatest eclipse took place over the open waters of the central North Pacific Ocean, northwest of the Cape Verde Archipelago, in the Northern  Hemisphere. The November 2002 penumbral lunar eclipse appears as number 57 in the series’ lineup of 73 lunar eclipses and as third in the closing sequence of 20 penumbral lunar eclipses in Saros series 116.

The penumbral eclipse of Saturday, Dec. 11, 2038, is the successor of November’s penumbral lunar eclipse in Saros series 116. This event’s greatest eclipse will take place over northeastern India, in southwestern Mizoram state, near the India-Myanmar border, in the Northern Hemisphere. This eclipse occurs as number 59 in the lineup of 73 lunar eclipses and sixth in the closing sequence of 20 penumbral lunar eclipses.

The takeaway for the Monday, Nov. 30, 2020, penumbral lunar eclipse is that the fourth of the year’s four penumbral lunar eclipses belongs to Saros series 116 and occurs as number 58 in the lineup of 73 lunar eclipses in the series.
