12 May    Look low in the west at evening twilight to find Jupiter 3 finger-widths to the lower right of the thin waxing crescent moon. Only 5 percent of the moon’s surface is illuminated.

13 May    The moon is at apogee, 63.63 earth-radii, or 406,000 kilometers, away.

15 May    Magnitude 0.5 Procyon is 1 fist-width below or to the lower left of the waxing crescent moon, and the Gemini Twins are the same distance to the moon’s upper right. About 25 percent of the moon’s surface is illuminated.

16 May    Tonight several prominent stars surround the waxing crescent moon, all about 2 fist-widths away: Procyon to the lower right, the Gemini Twins to the right, Regulus to the upper left and the slightly dimmer Alphard to the lower left. The Big Dipper is high overhead, far to the upper right.

17 May    Regulus is 3 finger-widths above the moon tonight.

18 May    The first-quarter moon is high in the southwest at dusk. Regulus is 1 fist-width to the upper right.

5 May    Leo, the Lion, dominates the southern sky. Its brightest star, magnitude 1.3 Regulus, is easy to spot in the south. Magnitude 0.5 Procyon is 4 fist-widths to Regulus’ lower right. Magnitude 2.2 Alphard, in the constellation Hydra, the Sea Serpent, is 2 fist-widths below Regulus. Magnitude 1.2 Spica lies far to the lower left of Regulus. Noticeably brighter, Saturn is just beyond Spica.

6 May    The bright star halfway up from the eastern horizon is magnitude 0.2 Arcturus, in the constellation Boötes, the Herdsman. Arcturus comes from the Greek, meaning “guardian of the bear.”

7 May    In the early evening, the Big Dipper is upside down high overhead with its handle extending to the right.

9 May    For the best view of today’s annular solar eclipse, you will have to go to Australia or New Guinea. Those in Hawaii will see a partial eclipse. New moon at 0028 UT

10 May    The moon sets less than an hour after the sun but if you have a clear view of the western horizon, you may be able to catch a glimpse of the thin waxing crescent moon just to the lower left of Venus.

13 Nov    Rising 2 hours after sunset, the waning gibbous moon stands high in the east before midnight with Orion to the lower right and Gemini to the lower left.

15 Nov    Low in the east at midnight, the moon is between magnitude 0.5 Procyon, 1 fist-width to the lower right, and the Gemini Twins, 1 fist-width to the upper left.

17 Nov    High in the south before dawn, the Gemini Twins are 2 fist-widths the moon’s upper right. Procyon is the same distance to the lower right. The brightest star in the area, magnitude 2.2 Alphard in the constellation Hydra the Sea Serpent is 2 fist-widths to the moon’s lower left. Magnitude 1.3 Regulus is 2 fist-widths to the moon’s left, and magnitude 0.9 Mars is less than 2 finger-widths to the left of Regulus.

18 Nov    This morning, Regulus is 4 finger-widths to the moon’s left. The brighter Mars is just beyond Regulus, and Procyon is 3 fist-widths to the moon’s lower right. Alphard is 1.5 fist-widths below the moon. Last-quarter moon at 1509 UT

19 Nov    Look for Regulus and Mars above the waning crescent moon just before dawn.

13 Mar    Using your binoculars, measure 1 finger-width to the moon’s lower right to find magnitude 3.2 mu Geminorum and 3 finger-widths to the moon’s lower left to find magnitude 1.9 Alhena, both in the constellation Gemini. Daylight saving time begins in most of the United States at 0200 as clocks are set one hour forward.

14 Mar    Procyon is a little more than 1 fist-width to the moon’s lower left tonight. The Gemini Twins are less than 1 fist-width above the moon. Mercury is 1 finger-width to Jupiter’s lower right low in the west at dusk.

15 Mar    Magnitude -1.1 Mercury is less than 1 finger-width to the upper right of magnitude -2.1 Jupiter at dusk. Today marks the Ides of March, when Julius Caesar was assassinated.

16 Mar    Tonight, Regulus is less than 1 fist-width to the moon’s lower left, and magnitude 2.2 Alphard is 2 fist-widths to the moon’s lower right.

17 Mar    Regulus is 3 finger-widths above the moon tonight. About 90 percent of the moon’s surface is illuminated. Today is St. Patrick’s Day.

19 Mar    Rising a half-hour after sunset, the full moon is followed by Saturn 1 fist-width to the lower left. Spica is 1 fist-width below Saturn, and Arcturus is 3 fist-widths to Saturn’s left. The moon is at perigee, less than 221,830 miles or 55.91 Earth-radii away. This is the moon’s closest approach of the year. Perigee occurs less than 1 hour after the full moon, so expect tidal extremes. Full Worm Moon at 1810 UT
