29 Dec    The moon is 4 finger-widths to Saturn’s lower left. Less than 20 percent of the moon’s surface is illuminated.

1 Jan    Rising a few minutes after sunset, Jupiter is high in the east by midevening. The Gemini Twins, Pollux and Castor, are less than 1 fist-width to the left, and Orion is about 3 fist-widths to the right. The bright star 2 fist-widths to the lower right is magnitude 0.5 Procyon. The new moon, only 9.8 hours old, is at perigee, 56.02 Earth-radii (357,000 kilometers) away. Check your tide tables.

2 Jan    Occurring a day after the new moon, the Quadrantids meteor shower should be above average and can be viewed over five nights. At its peak from the evening of 2 Jan. to the morning of 3 Jan, you may see 60-200 meteors per hour. For best viewing, choose a dark location after midnight. Meteors can appear anywhere in the sky but will radiate from the constellation Boötes, which rises above the eastern horizon shortly after midnight. This is the only one of the three dominant meteor showers (Quadrantids, Perseids and Geminids) on a moonless night.

4 Jan    At perihelion, Earth makes its closest approach to the sun for the year at 0.98333 AU, or about 91.4 million miles, away. An astronomical unit (92,955,807.3 miles) is the average distance from Earth to the sun.
