Passing this on from a post by Eric Jamison on Cloudynights. For a period of about 1 1/2 hours on Tuesday, two of Jupiters moons will be behind the planet, and one in front, leaving only Callisto off to the side. This event is sort of rare. It favors locations east of Arizona, but we will be able to see it here after sunset The time range is defined by the period between Io's disappearance Ganymede's reappearance, which is 5:41 p.m. to 7:12 p.m. MST. Sunset is at 6:45 p.m., and you should be able to pick up Jupiter by 7:00.
