The first lunar eclipse of 2012 occurs at the Moon’s ascending node in southern Ophiuchus about 6° northeast of Antares (mv = +1.07). It is best seen from locations in and near the Pacific Ocean (Figure 3). Most of the Americas will experience moonset before the eclipse ends while eastern Asia will miss the beginning of the eclipse because it occurs before moonrise. The Moon’s contact times with Earth’s shadows are listed below.
Penumbral Eclipse Begins: 08:48:09 UT
Partial Eclipse Begins: 09:59:53 UT
Greatest Eclipse: 11:03:13 UT
Partial Eclipse Ends: 12:06:30 UT
Penumbral Eclipse Ends: 13:18:17 UT
At the instant of greatest eclipse the umbral eclipse magnitude will reach 0.3705. At that time the Moon will be at the zenith for observers in the South Pacific. In spite of the fact that just a third of the Moon enters the umbral shadow (the Moon’s southern limb dips 12.3 arc-minutes into the umbra), the partial phase still lasts over 2 hours.
