The first quarter moon is Dec. 3. As Jupiter disappears into bright twilight by mid-December, Venus is still moving away from the Sun and passes within two degrees south of Saturn on December 11. The Full Moon, the Yule Moon, is also that Wednesday evening. The waning gibbous moon will interfere with the peak of the Geminid meteor shower on the morning of Dec. 14.The last quarter moon is on Dec. 18.

The moon is a slender waxing crescent for Halloween setting in the west about the time that trick or treaters should be getting worn out. So get out the scopes and give your guests a telescopic treat as well, with Jupiter just south of the moon, and Saturn east of them in the western twilight.
