16 Dec    In the southwest at dusk, the thin waxing crescent moon is about 10 percent illuminated.

18 Dec    High in the southwest early tonight, magnitude 1.3 Deneb in the constellation Cygnus, the Swan, is more than 5 fist-widths to the moon’s upper right. In one story, Orpheus, who sang and played his lyre so beautifully that wild animals and trees came to hear him, was transformed into a Swan after his death and placed next to his lyre, Lyra.

20 Dec    The Great Square of Pegasus is above the first-quarter moon at dusk.

21 Dec    High in the south tonight, the moon is surrounded by many lower-magnitude stars. About 3 hours after sunset, magnitude 2.1 Alpheratz is a little more than 2 fist-widths to the moon’s upper right. Magnitude 2.0 Mira is 2 fist-widths to the moon’s lower left. Magnitude 2.2 Deneb Kaitos is 3 fist-widths below the moon, and magnitude 2.2 Hamal is 1½ fist-widths to the moon’s upper left. Today marks the first day of winter, the winter solstice, as the sun reaches its farthest distance below the celestial equator. This is the last day of the 13th baktun in the Long Count of the Mayan Calendar. The official end is 1111 UT.

22 Dec    Today is the first day of the 14th baktun in the Long Count of the Mayan Calendar.
