A total eclipse of the Moon happens before or during dawn Saturday morning for the western half of North America; the farther west you are the better. It happens during Saturday evening for Australia and the Far East. This eclipse is barely total and for only about 12 minutes, from about 11:54 to 12:06 April 4th UT (GMT). Partial eclipse begins at 10:15 UT and ends at 13:45 UT. For maps and more, see the April Sky & Telescope, page 50, or the version online: Preview of April 4th’s Total Lunar Eclipse.
Can’t see it from where you are? Griffith Observatory in Los Angeles will run a live webcast from 11:00 p.m. to 3:30 a.m. Eastern Daylight Time (4:00 to 7:30 April 4th UT).
On Friday evening for North America, the full Moon shines in Virgo with Spica well to its lower left, as shown here. Much closer to the Moon is fainter Gamma Virginis (Porrima), a close telescopic double star.
Look above Venus at nightfall for the Pleiades star cluster, the size of your fingertip at arm’s length. It’s 8° above Venus this evening. It will pass Venus by less than 3° on April 10th through 12th.
The coming of April always finds Orion in the southwest at dusk, leaning over with his three-star belt almost horizontal (depending on your time and latitude). The belt points left toward bright Sirius, and to the right toward Aldebaran and, farther on, the Pleiades.
The waxing gibbous Moon shines beneath Regulus and the Sickle of Leo early this evening, as shown at right. Farther upper right of the Moon shines bright Jupiter. By late evening, the sky rotates to place Jupiter to the Moon’s right.
The shadow of Callisto slowly crosses Jupiter’s face tonight from 11:14 p.m. to 3:57 a.m. EDT.
Watch Jupiter’s satellite Europa emerge out of eclipse from Jupiter’s shadow around 11:01 p.m. Eastern Daylight Time. With a telescope, watch for it to gradually glimmer into view a little off Jupiter’s celestial eastern (following) limb.
Tonight the Moon and Jupiter cross the sky together. Although they look fairly near each other, looks in astronomy are deceiving. Jupiter is almost 1,800 times farther away than the Moon, and it’s 40 times larger in diameter.
Now the Moon has moved inside the triangle of Jupiter, Pollux, and Procyon.
This evening the Moon forms a big kite shape with bright Jupiter far to its left, Pollux to the Moon’s upper left, and Procyon to its lower left
