First Lunar Eclipse 2010
The first lunar eclipse 2010 occurs at the Moon’s ascending node in western Sagittarius about 3° east of the Lagoon Nebula (M8). It is visible from much of the Americas, the Pacific and eastern Asia. The Moon’s contact times with Earth’s shadows are listed below.
Penumbral Eclipse Begins: 08:57:21 UT
Partial Eclipse Begins: 10:16:57 UT
Greatest Eclipse: 11:38:27 UT
Partial Eclipse Ends: 12:59:50 UT
Penumbral Eclipse Ends: 14:19:34 UT
At the instant of greatest eclipse4 the umbral eclipse magnitude5 will reach 0.5368. At that time the Moon will be at the zenith for observers in the South Pacific. In spite of the fact that barely half of the Moon enters the umbral shadow (the Moon’s northern limb dips 16.2 arc-minutes into the umbra), the partial phase still lasts 2 2/3 hours.
The June 26 partial lunar eclipse belongs to Saros 120, a series of 83 eclipses in the following sequence: 21 penumbral, 7 partial, 25 total, 7 partial, and 23 penumbral lunar eclipses.
