FRIDAY, JANUARY 15
■ The crescent Moon hangs in the southwest after sunset, as shown below. It aims its curve lower right almost at Mercury, like a bow ready to shoot an arrow. Mercury is about two fists at arm’s length from it (during twilight in North America).
Even farther down in the same direction, can you still pick out Jupiter with binoculars? Jupiter is now very nearly on the opposite side of the Sun from us.
Day by day, the waxing crescent Moon in twilight steps up and away up from low Mercury and super-low Jupiter.
■ Once full night
