Last night the moon shone to the left of Saturn. Tomorrow night, it will be in conjunction with Mars, gliding only 4° to its north. Although fading a bit, Mars is still a couple tenths of a magnitude brighter than Sirius, the brightest star, and maintains its eye appeal as we head toward the first day of fall. When you’re out moongazing, a pair binoculars magnifying 10x will easily show craters, particularly along the terminator, where sunlight strikes the moon’s surface at a glancing angle. The combination of sun-struck highlights and long shadows helps to outline and clearly define these enormous impact holes.
