10 Dec    The waning crescent moon is 2 finger-widths to Saturn’s lower right this morning.

11 Dec    Before first light, the moon is 1 finger-width to the Venus’ lower right, and Mercury is 3 finger-widths to its lower left.

12 Dec    The moon has now passed Mercury and is quickly lost in dawn’s early light. The moon is at perigee, 55.99 Earth-radii (357,000 kilometers) away.

13 Dec    The Geminid meteor shower peaks tonight with no moon to interfere, making this a good viewing opportunity.

14 Dec    Look low in the west at dusk to see Mars 3 finger-widths to the left or upper left of the thin waxing crescent moon. Only a thin sliver of the moon is illuminated.

15 Dec    Mars is 4 finger-widths below the moon tonight. Only about 5 percent of the moon’s surface is illuminated.
