1 Apr    Early tonight, Regulus is 1½ fist-widths to the moon’s upper right high in the east, and Jupiter is another 1½ fist-widths beyond Regulus.

2 Apr    In the east, Jupiter, Regulus, the moon and Spica line up from upper right to lower left late tonight.

4 Apr    This morning brings a total lunar eclipse. The eclipse begins as the moon enters Earth’s umbra at 1015 UT.

8 Oct    A total lunar eclipse will be visible for much of the U.S. before dawn as Earth’s shadow covers the full moon.

10 Oct    Rising less than 2 hours after sunset, the waning gibbous moon is high in the east by midnight. You may need binoculars to see the Pleiades Cluster is 1 fist-width to the left.

11 Oct    The moon rises 2½ hours after sunset and is followed a few minutes later by magnitude 1.1 Aldebaran. By midnight, they have climbed higher in the east with Aldebaran 1 finger-width to the moon’s lower left. The Pleiades Cluster is 1 fist-width above the moon.

13 Apr    High in the southwest by late evening, Mars is 3 finger-widths to the moon’s lower left, and Spica is 4 finger-widths below Mars.

14 Apr    Only 0.618 AU (92.4 million kilometers) away, Mars makes its closest approach to Earth since January 2008. By midnight, Spica and the moon are high in the southwest, less than ½ finger-width apart.

15 Apr    During April’s full moon, North America will see a total lunar eclipse beginning at about 0200 EDT. Totality begins an hour later and lasts 1 hour and 20 minutes. The moon completely leaves Earth’s umbra at 0533 EDT.

16 Apr    Low in the east at midnight, Saturn is ½ finger-width to the moon’s left. The nearly full moon will likely outshine Saturn, so get out your binoculars. At the southern tip of South America, the moon occults Saturn tomorrow morning.

17 Apr    Saturn stands 1 finger-width to the moon’s right before dawn.

18 Apr    Low in the south before dawn, magnitude 1.1 Antares is 3 finger-widths to the moon’s lower left and Saturn is 1½ fist-widths to the lower right.

4 Dec    Jupiter is 2 fist-widths to the moon’s left or lower left tonight. The moon is two-thirds illuminated.

5 Dec    Tonight Jupiter is only 4 finger-widths to the moon’s left.

6 Dec    The moon passes Jupiter tonight 3 finger-widths to the planet’s upper left. The moon is at apogee 63.56 Earth-radii, or 405,000 kilometers, away.

7 Dec    Late tonight, the moon is high in the southeast between Jupiter, 1.5 fist-widths to the right or upper right, and the Pleiades, 1 fist-width to the lower left. Orion is to the lower left, closer to the horizon.

8 Dec    The Pleiades Cluster is only 1 finger-width to the upper left of the nearly full moon, making viewing difficult.

9 Dec    Using binoculars, look for magnitude 1.1 Aldebaran 3 finger-widths to the moon’s lower right late tonight. The Pleiades Cluster is more than 1 fist-width to the moon’s upper right, making viewing much easier.

10 Dec    The total lunar eclipse will appear as a partial eclipse in most of the United States. The best viewing will be in the Pacific Northwest, Alaska and Hawaii. Full moon at 1436 UT

21   The winter solstice occurs at 2338 UT as the sun reaches its farthest point south. Today marks the shortest day and longest night of the year. This morning, a total lunar eclipse is visible across North America and most of the eastern Pacific, including Hawaii. The eclipse begins at 0632 UT when the umbra first touches the moon. Totality begins at 0740 UT and lasts until 0854 UT. The last bit of shadow leaves the moon at 1002 UT. Unlike solar eclipses, lunar eclipses are completely safe to watch. Full Cold moon at 0813 UT
