20 May    The moon lies midway between Venus, 1 fist-width above, and Betelgeuse, below or to the lower left.

21 May    Low in the west at dusk, Venus is 4 finger-widths to the moon’s right. Procyon is 1 fist-width to the left or lower left.

22 May    The moon lies in the middle of a triangle formed by Venus, 1½ fist-widths to the lower right, Procyon, 1 fist-width below, and Jupiter, 1½ fist-widths to the upper left. Saturn reaches opposition at 2200 EDT. Lining up opposite the sun, it rises around sunset and sets around sunrise.

23 May    Jupiter is 2 finger-widths to the moon’s upper right tonight.

4 Jan    Earth is at perihelion, 0.98328 AU away from the sun. Compare that to Earth’s distance of 1.01668 AU from the sun at aphelion on 6 July. An astronomical unit, or AU, is about 150,000,000 km or 93,000,000 miles.

5 Jan    As evening passes, it should be easy to spot the Gemini Twins 1 fist-width to the moon’s upper left and Procyon the same distance to the lower right.

6 Jan    High in the east by midnight, Jupiter is about 1 fist-width to the moon’s lower left. Procyon is 1½ fist-widths to the upper right.

7 Jan    By midnight, the moon, Jupiter and Regulus form a tight triangle in the east, with Jupiter 2 finger-widths to the moon’s upper left and Regulus 4 finger-widths to the moon’s lower left. The Big Dipper stands on its handle to the left.

8 Jan    Jupiter is directly above the moon low in the east by midnight, and Regulus is to the moon’s upper left.

9 Jan    The moon forms a nearly straight line with Regulus, 1½ fist-widths above, and Jupiter, less than 1 fist-width beyond.

10 Jan    High in the southwest before dawn, the moon lies between Regulus, 2 fist-widths to the right, and Spica, 3½ fist-widths to the left.

17 Aug    This morning, Jupiter rises 5 minutes after Venus, less than a half a finger-width away. High in the southeast before dawn, the last-quarter moon forms a line with 3 first-magnitude stars: magnitude 1.1 Aldebaran 1½ fist-widths to the lower left, magnitude 0.6 Betelgeuse 2 fist-widths beyond Aldebaran, and magnitude 0.5 Procyon 2½ fist-widths farther, near the horizon.

18 Aug    Rising a minute later than Jupiter, Venus slides to Jupiter’s left this morning as they pass within 0.21 degrees. Aldebaran is 2 finger-widths to the waning crescent moon’s lower left. The Pleiades Cluster is 1 fist-width above the moon.

19 Aug    Venus quickly falls away from Jupiter. Separated by a half a finger-width, Venus rises 6 minutes after Jupiter. Betelgeuse is 1½ fist-widths below the moon this morning.

20 Aug    Before dawn Betelgeuse is 1 fist-width to the moon’s lower right, and Procyon is 2½ fist-widths below the moon.

21 Aug    The Gemini Twins, Pollux and Castor, are 1½ fist-widths to the moon’s left before dawn. Pollux is the brighter twin. The second-magnitude star 2 finger-widths to the moon’s upper right is magnitude 1.9 Alhena, also in Gemini. Low in the south early tonight, Mars and Saturn are 1½ fist-widths to the right of Scorpius’ head. Mars is 2 finger-widths to Saturn’s lower right and slides to the left during the next few nights.

22 Aug    The waning crescent moon lies between Procyon, 1 fist-width to the lower right, and Pollux, a little farther to the upper left. Less than 10 percent of the moon’s surface is illuminated.

23 Aug    Rising 1½ hours before the sun, the moon, Venus and Jupiter are clustered within 4 finger-widths near the horizon at first light. Mars is directly below Saturn tonight. The third-magnitude star 1 finger-width to Mars’ upper right is magnitude 2.9 Zubenelgenubi, which represents the top of Libra’s scales.
