The Friday, June 5, penumbral lunar eclipse belongs to Saros series 111, which comprises 71 lunar eclipses with similar geometries.

June’s penumbral lunar eclipse begins Friday, June 5, at 17:45:50 Universal Time (1:45 p.m. Eastern Daylight Time), according to NASA’s Eclipse Web Site. Greatest eclipse, which designates the instant of the moon’s closest passage to the axis of Earth’s shadow, takes place at 19:25:02.0 UT (3:25 p.m. EDT). The eclipse ends at 21:04:03 UT (5:04 p.m. EDT).

June’s penumbral lunar eclipse appears as number 67 in the lineup of 71 lunar eclipses in Saros series 144. Similar geometries group the 71 lunar eclipses into a family, known as a series.

Saros 111 lunar eclipses share the geometry of occurrence at the moon’s descending node. With each subsequent eclipse, the lunar movement in Saros series 111 is northward with respect to the descending node.

A pair of nodes mark the intersections of Earth’s orbit with the lunar orbit. The two nodes reveal the approximately 5.1 degree tilt of the lunar orbit with respect to Earth’s orbit. An ascending node corresponds with the lunar orbital crossing to the north of Earth’s orbit. A descending node associates 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), decides the periodicity and recurrence of eclipses. A Saros series contains 70 or more lunar eclipses, each separated by a Saros cycle. A Saros series has a typical duration of 12 to 15 centuries.

Saros series 111 covers a time span of 1,262.11 years. Saros series 111 stretches across 13 centuries, beginning in the 9th century and ending in the 21st century.

The 71 lunar eclipses in Saros series 111 appear in a sequence of nine penumbral lunar eclipses, 20 partial lunar eclipses, 11 total lunar eclipses, 23 partial lunar eclipses and eight penumbral lunar eclipses. Partial lunar eclipses claim the greatest frequency in Saros series 111, with a total of 43 occurrences. Penumbral lunar eclipses appear as the second most frequent lunar eclipse type in the series, with a total of 17 occurrences.

The 9th century’s penumbral eclipse of Friday, June 10, 0830, opened Saros series 111. This eclipse occurred near the southern edge of the penumbra, the shadow’s lighter, outer region. This event staged its greatest eclipse over the open waters of the eastern South Pacific Ocean, west of the South American Republic of Chile, in the Southern Hemisphere.

The 21st century’s penumbral eclipse of Saturday, July 19, 2092, ends Saros series 111. This eclipse will occur near the penumbra’s northern edge.

The Friday, June 5, 2020, penumbral lunar eclipse occurs as number 67 within the lineup of 71 lunar eclipses in Saros series 111. June’s penumbral lunar eclipse numbers as fourth in the closing sequence of eight penumbral lunar eclipses in Saros series 111. This event will experience its greatest eclipse over the open waters of the central South Indian Ocean, in the Southern Hemisphere.

The penumbral lunar eclipse of Sunday, May 26, 2002, is the immediate predecessor of June’s penumbral lunar eclipse. This event’s greatest eclipse took place over the open waters of the southwestern Pacific Ocean, north of New Zealand and east of France’s special collectivity of New Caledonia (Nouvelle-Calédonie), in the Southern Hemisphere. The May 2002 penumbral lunar eclipse appears as number 66 in the series’ lineup of 71 lunar eclipses and as third in the closing sequence of eight penumbral lunar eclipses.

The penumbral eclipse of Thursday, June 17, 2038, is the successor of June’s penumbral lunar eclipse. This event’s greatest eclipse will take place over the western South Atlantic Ocean, offshore of southeastern Brazil’s Northern Fluminense mesoregion (Mesorregião do Norte Fluminense) in northern Rio de Janeiro state, in the Southern Hemisphere. This eclipse occurs as number 68 in the lineup of 71 lunar eclipses and as number five in the closing sequence of eight penumbral lunar eclipses.

The takeaway for the Friday, June 5, 2020, penumbral lunar eclipse is that the second of the year’s four penumbral lunar eclipses belongs to Saros series 111 and occurs as number 67 in the lineup of 71 lunar eclipses in the series.
