June 1, 2011, Partial Solar Eclipse Belongs to Saros Series 118

Summary: The Wednesday, June 1, 2011, partial solar eclipse belongs to Saros cycle 118, a series of 72 similar solar eclipses.

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.

Partial solar eclipse of July 15, 2083, will close Saros solar series 118’s lineup of 72 solar eclipses: "Permission is freely granted to reproduce this data when accompanied by an acknowledgment, Eclipse Predictions by Fred Espenak (NASA's GSFC)," via NASA Eclipse Web Site

Second of Four 2011 Partial Solar Eclipses Happens Wednesday, June 1

Summary: The second of four 2011 partial solar eclipses happens Wednesday, June 1, with the Northern Hemisphere’s high latitudes favored for visibility.

The second of four 2011 partial solar eclipses happens Wednesday, June 1, with the path of visibility favoring the Northern Hemisphere’s high latitudes.

On the NASA Eclipse Web Site, retired astrophysicist Fred Espenak, known as “Mr. Eclipse,” observes that the June 2011 partial solar eclipse entails partial obscuring of the midnight sun in areas in Scandinavia that lie above the Arctic Circle. Partial eclipses of the midnight sun occur for Finland, Iceland, Norway and Sweden.

In North America, most of Alaska and northern Canada fall within the partial solar eclipse’s visibility path. The path’s southern limit across Earth’s surface curves from south of Fairbanks in east central Alaska to eastern Canada’s central New Brunswick and Nova Scotia.

From Earth’s perspective, a solar eclipse ensues from the moon’s passage between Earth and the solar system’s sun. A partial obscuring of the solar image produces a partial solar eclipse for observers on Earth.

First touching of Earth’s surface by the moon’s penumbra marks the beginning of the second of four 2011 partial solar eclipses. The penumbral shadow’s first touches take place Wednesday, June 1, at 19:25:18 Universal Time (3:25:18 p.m. Eastern Daylight Time). P1 is the designator for the instant of first touches by the penumbra, the shadow’s lighter, outer region.

The NASA Eclipse Web Site indicates sunrise in northern China and in Siberia as points of first touches on the Earth’s surface.

Greatest eclipse takes place Wednesday, June 1, at 21:16:11 UT (5:16:11 p.m. EDT). Greatest eclipse represents the instant of closest passage of the axis of the lunar shadow cone to Earth’s center.

The penumbra’s last touching of Earth’s surface marks the eclipse’s end. Exit from the moon’s penumbral shadow happens Wednesday, June 1, at 23:06:56 UT (7:06:56 p.m. EDT). P4 is the designator for the last penumbral contact with Earth’s surface.

“Mr. Eclipse” notes that the penumbra last touches Earth’s surface over water. Last contact takes place in the Atlantic Ocean, just north of Newfoundland.

The June 2011 partial solar eclipse belongs to Saros 118. According to the Saros cycle, lunar eclipses and solar eclipses belong to families, known as series. A Saros cycle covers approximately 6,585.3 days (18 years 11 days 8 hours).

The second of four 2011 partial solar eclipses happens five and one-third months after the year’s first partial solar eclipse. The Tuesday, Jan. 4, partial solar eclipse opened the eclipse lineup. The year’s third and fourth partial solar eclipses take place Friday, July 1, and Friday, Nov. 25, respectively.

The 2011 eclipse lineup presents a rare 4:2 combination of four solar eclipses and two lunar eclipses. Only six years in the 21st century exhibit the 4:2 combination: 2011, 2029, 2047, 2065, 2076 and 2094.

The year’s two lunar eclipses are both total. The first of 2011’s two total lunar eclipses occurs Wednesday, June 15. The second total lunar eclipse closes the 2011 eclipse lineup on Friday, Dec. 10.

The 2011 lineup of four partial solar eclipses also distinguishes the year. Only six years in the 21st century experience four solar eclipses. The number of annual solar eclipses ranges from a minimum of two per year to a maximum of five per year.

Observers along the path of visibility should remember that direct viewing of partial solar eclipses is unsafe. Use of proper equipment and following of proper techniques are necessary for safe viewing of partial solar eclipses.

The takeaway for the second of four 2011 partial solar eclipses, which happens Wednesday, June 1, is the event’s favoring of the Northern Hemisphere’s high latitudes for visibility.
