The second 2018 total lunar eclipse occurs Friday, July 27, at 17:14:49 Coordinated Universal Time (1:14 p.m. Eastern Daylight Time; 1:14 p.m. Atlantic Standard Time; 2:44 p.m. Newfoundland Daylight Time), as last of 2018’s two lunar eclipses and as fourth of five 2018 eclipses.

July’s lunar eclipse begins with a penumbral eclipse. The instant of first exterior contact between Earth’s penumbra and the moon initiates the penumbral eclipse. The penumbra is the lighter, outer region of Earth’s shadow.

The lunar eclipse ends at 23:28:37 UTC (7:28 p.m. AST/EDT; 8:58 p.m. NDT) with the instant of last exterior contact between Earth’s penumbra and the moon. The total lunar eclipse lasts approximately 6 hours 13 minutes 48 seconds.

A partial eclipse commences at 18:24:27 UTC (2:24 p.m. AST/EDT; 3:54 p.m. NDT) with the instant of first exterior contact between Earth’s umbra and the moon. The umbra is the darker, inner region of Earth’s shadow.

The full eclipse begins at 19:30:15 UTC (3:30 p.m. AST/EDT; 5 p.m. NDT) with the instant of first interior contact between Earth’s umbra and the moon. Greatest eclipse takes place at 20:21:44 UTC (4:21 p.m. AST/EDT; 5:51 p.m. NDT). Greatest eclipse represents the instant of the moon’s closest passage to the axis of Earth’s shadow.

Totality ends at 21:13:12 (5:13 p.m. AST/EDT; 6:43 p.m. NDT) with the instant of last interior contact between Earth’s umbra and the moon. Totality spans almost 1 hour 43 minutes (1 hour 42 minutes 57 seconds).

Partiality ends at 22:19:00 UTC (6:19 p.m. AST/EDT; 7:49 p.m. NDT). The instant of last exterior contact between Earth’s umbra and the moon signals the end of the partial eclipse.

The penumbral eclipse ends at 23:28:37 UTC (7:28 p.m. AST/EDT; 8:58 p.m. NDT), with the last exterior contact between Earth’s penumbra and the moon. The ending of the penumbral eclipse brings closure to the second 2018 total lunar eclipse.

July’s lunar eclipse has a total duration of 6 hours 13 minutes 48 seconds. The year’s second total lunar eclipse lasts 56 minutes 36 seconds longer than the year’s first total lunar eclipse. January 2018’s total lunar eclipse’s duration was 5 hours 17 minutes 12 seconds.

July’s totality of 1 hour 42 minutes 56 seconds exceeded January’s totality by 26 minutes 52 seconds. January’s totality endured 1 hour 16 minutes 4 seconds.

The second 2018 total lunar eclipse favors the Indian Ocean. Oceanically, eclipse visibility also encompasses the Southern Ocean and much of the Atlantic and the Pacific.

Continentally, July’s total lunar eclipse favors Antarctica, Central Asia and Eastern Africa. Eclipse visibility at moonrise is available for much of Europe, western Africa and South America. Australia and eastern Asia experience eclipse visibility at moonset.

Eclipse visibility excludes continental North America. The northeastern island of Newfoundland claims Canada’s only visibility, with a moonrise eclipse. The United States finds visibility only in the Caribbean Sea. The U.S. territories of Puerto Rico and the U.S. Virgin Islands experience the eclipse at moonrise.

July’s total lunar eclipse closes the lunar component of 2018’s eclipse offerings. The next lunar eclipse occurs almost six months later, on Monday, Jan. 21, 2019.

The first 2019 lunar eclipse occurs as another total eclipse. The second 2019 lunar eclipse appears as a partial eclipse.

July’s total lunar eclipse numbered fourth in 2018’s lineup of five eclipses. As the year’s second lunar eclipse, the July event is sandwiched between two solar eclipses.

The year’s last lunar eclipse shared the month of July with 2018’s second partial solar eclipse. The month’s partial solar eclipse happened Friday, July 13, two weeks before the month’s lunar eclipse.

The year’s fifth and last eclipse takes place Saturday, Aug. 11. The August event numbers as the third of three 2018 partial solar eclipses.

The 21st century’s next solar eclipse happens Sunday, Jan. 6, 2019, as a partial eclipse. January’s solar eclipse opens 2019’s quintet of eclipses. The 2019 solar lineup features three different eclipses: partial, total and annular.

The takeaway for the second 2018 total lunar eclipse is that its occurrence Friday, July 27, falls between the year’s last two solar eclipse and marks the year’s last lunar eclipse.

First 2018 Eclipse Is Blue Moon Total Lunar Eclipse Wednesday, Jan. 31

Summary: The first 2018 eclipse is the blue moon total lunar eclipse Wednesday, Jan. 31, happening during January’s second full moon, known as a blue moon.

The first 2018 eclipse is a blue moon total lunar eclipse Wednesday, Jan. 31, that happens during January’s second full moon, known as a blue moon.

The blue moon lunar eclipse of Wednesday, Jan. 31, begins at 10:51:15 Coordinated Universal Time (12:51:15 a.m. Hawaii-Aleutian Standard Time) with the instant of first exterior contact between the moon and Earth’s penumbra, the lighter, outer region of Earth’s shadow. The event ends at 16:08:27 UTC (6:08:27 a.m. HAST) with the instant of last exterior contact between moon and Earth’s penumbra. The blue moon lunar eclipse lasts for 5 hours 17 minutes 12 seconds.

The partial phase of the blue moon total lunar eclipse Wednesday, Jan. 31, begins at 11:48:27 UTC (1:48:27 a.m. HAST) with the instant of first exterior contact between the moon and Earth’s umbra, the darker, inner region of Earth’s shadow. Partiality ends at 15:11:11 UTC (5:11:11 a.m. HAST) with the instant of last exterior contact between the moon and Earth’s umbra. Partiality’s time span is 3 hours 22 minutes 44 seconds.

The total phase of the blue moon total lunar eclipse Wednesday, Jan. 31, begins at 12:51:47 UTC (2:51:47 a.m. HAST) with the instant of first interior contact between the moon and Earth’s umbra. Totality ends at 14:07:51 UTC (4:07:51 a.m. HAST) with the instant of last interior contact between the moon and Earth’s umbra. Totality’s time span is 1 hour 16 minutes 4 seconds.

For lunar eclipses, greatest eclipse references the instant of the moon’s closest passage to the axis of Earth’s shadow. The greatest eclipse for the blue moon total lunar eclipse Wednesday, Jan. 31, takes place at 13:29:51 UTC (3:29:51 a.m. HAST). Retired NASA astrophysicist Fred Espenak's EclipseWise web site places the greatest eclipse's occurrence over the South Pacific Ocean, about 1,800 miles (2,900 kilometers) west of the Hawaiian Islands.

The blue moon total lunar eclipse Wednesday, Jan. 31, centers on the Pacific Ocean. Oceanically, entire eclipse visibility also favors the Arctic Ocean. Continentally, eclipse visibility from beginning to end favors central and eastern Asia, most of Australia and far northern North America.

In North America, Canada experiences entire eclipse visibility throughout Yukon Territory and in much of the Northwest Territories and Nunavut. Most of British Columbia and the northwestern corner of Alberta also enjoy entire eclipse visibility. Entire eclipse visibility favors only two U.S. states: Alaska on the North American mainland and Hawaii in the Pacific Ocean.

Arctic Ocean and Pacific Ocean islands are favorably sited for entire eclipse visibility. Northern Greenland joins Canada’s, Norway’s and Russia’s Arctic islands in the entire eclipse experience. In Maritime Southeast Asia, all of New Guinea and the Philippines and much of Borneo participate in entire eclipse visibility. Other Pacific island nations favored by entire eclipse visibility include Japan, New Zealand and Samoa.

Oceanic areas with no eclipse visibility at all include most of the Atlantic Ocean and the Southern Ocean. Continentally, most of the continents of Africa, Antarctica, Europe and South America are excluded for eclipse visibility.

The blue moon total lunar eclipse Wednesday, Jan. 31, opens the 2018 eclipse quintet of two total lunar eclipses and three partial solar eclipses. The year’s second total lunar eclipse happens Friday, July 27, and favors the Indian Ocean and adjacent continents.

The year’s first partial solar eclipse succeeds 2018’s first total lunar eclipse. The first partial solar eclipse takes place Thursday, Feb. 15, as a Southern Hemisphere event favoring Antarctica and southern South America. The year’s second partial solar eclipse happens Friday, July 13, as a Southern Hemisphere event favoring the Southern Ocean and southeastern Australia.

The year’s third partial solar eclipse follows 2018’s second total lunar eclipse and also closes the year’s eclipse lineup. The third partial solar eclipse occurs Saturday, Aug. 11, as a Northern Hemisphere event especially favoring the Arctic Circle.

As the first 2018 eclipse, the blue moon total lunar eclipse Wednesday, Jan. 31, stands out as an eclipse favoring both Southern and Northern Hemispheres and especially as a lunar eclipse coinciding with a blue moon.
