The Wednesday, June 1, 2011, partial solar eclipse belongs to Saros cycle 118, which comprises 72 solar eclipses with similar geometries.

Early June’s partial solar eclipse begins Wednesday, June 1, 2011, at 19:25:18 Universal Time (3:25:18 p.m. Eastern Daylight Time), according to the NASA Eclipse Web Site. The instant of the closest passage of the lunar shadow cone’s axis to Earth’s center, known as the greatest eclipse, occurs 1 hour 50 minutes 53 seconds later, at 21:16:11 UT (5:16:11 p.m. EDT). The eclipse ends at 23:06:56 UT (7:06:56 p.m. EDT).

June 2011’s partial solar eclipse appears as number 68 in the lineup of 72 solar eclipses that compose Saros cycle 118. Similar geometries gather the 72 solar eclipses into a family, known as a series.

The NASA Eclipse Web Site describes Saros 118 solar eclipses as sharing the geometry of occurring at the moon’s descending node. With each succeeding eclipse in Saros 118, the lunar movement is northward of the descending node.

A pair of ascending and descending nodes signal the intersections of Earth’s orbit by the moon’s orbit. The two nodes are associated with the approximately 5.1 degree tilt of the moon’s orbit with respect to Earth’s orbit. The ascending node concerns the lunar orbital crossing to the north of Earth’s orbit. The descending node links with 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) applies to the periodicity and recurrence of solar eclipses. Each Saros series contains 70 or more eclipses that typically occur over 12 to 13 centuries.

Saros solar series 118 endures for 1,280.14 years, according to the NASA Eclipse Web Site. The series traverses 13 centuries. The ninth through the 21st centuries frame Saros solar series 118.

Solar eclipses in Saros series 118 presents a sequence order of 8 partial solar eclipses, 40 total solar eclipses, 2 hybrid solar eclipses, 15 annular solar eclipses and 7 partial solar eclipses. Total solar eclipses contribute the most number of eclipses to Saros series 118, with a total of 40 occurrences. Partials and annulars tie as the second most frequent solar eclipse type in the series, with each accounting for 15 occurrences.

The ninth century’s partial solar eclipse of May 24, 803, opened Saros solar series 118. This Southern Hemisphere event's greatest eclipse, with coordinates of 68.1 south at 0.7 west, occurred over the Southern Ocean, north of East Antarctica's Fimbul Ice Shelf.

The 21st century’s partial solar eclipse of Thursday, July 15, 2083, ends Saros solar series 118. This Northern Hemisphere event's greatest eclipse, with coordinates of 64.0 north at 37.7 west, will take place over the North Atlantic Ocean, off southeastern Greenland.

June 2011’s partial solar eclipse occurs as the third within the closing sequence of seven partial solar eclipses in Saros series 118. This Northern Hemisphere event stages its greatest eclipse, with coordinates of 67.8 north at 46.8 east, over the Barents Sea, off northwestern Russia's Kanin Peninsula.

The partial solar eclipse of Friday, May 21, 1993, was the immediate predecessor of June 2011’s partial solar eclipse in the Saros solar series 118. This Northern Hemisphere event experiences its greatest eclipse, with coordinates of 68.8 north at 162.3 east, over northeastern Sakha Republic in the Russian Far East Federal District.

The May 1993 eclipse numbered as the second within the closing sequence of seven partial solar eclipses in Saros solar series 118. This eclipse claimed number 67 within the series’ lineup of 72 solar eclipses.

The successor of June 2011’s partial solar eclipse in Saros series 118 will appear Tuesday, June 12, 2029. This Northern Hemisphere event's greatest eclipse, with coordinates of 66.8 north at 66.2 west, occurs over Nunavut's Auyuittuq National Park, Baffin Island's Cumberland Peninsula, Qikiqtaaluk Region, in the Canadian Arctic Archipelago.

The June 2029 eclipse numbers as fourth within the closing sequence of seven partial solar eclipses in Saros solar series 118 and as number 69 within the series’ lineup of 72 solar eclipses.

The takeaway for the June 1, 2011, partial solar eclipse is that the event appears as number 68 in Saros solar series 118’s lineup of 72 solar eclipses and as the third occurrence in the series’ closing sequence of seven partial solar eclipses.
