■ Full Moon (exact at 6:08 p.m. EST). The Moon rises in the east-northeast just before sunset. After nightfall you can see that it shines between the hearts of the Gemini stick figures, if you use binoculars to help piece out the constellation through the moonlight. See the illustration below.
The Moon also forms a nice, more or less isosceles triangle with Castor and Pollux, Gemini's head stars, to its left. Watch this triangle change shape a bit through the night as the Moon moves eastward along its orbit: toward the Moon for Jan. 7 in the scene below.
