September 2nd through the 3rd. One will be able to see Jupiter without Moons. Jupiter can usually be seen with all or some of its four largest moons in binoculars and small telescopes however this is a very rare occurrence for it to be seen otherwise. But late on this night in most of the Western Hemisphere, the planet will be visible with no moons for nearly two hours.
Go take a look and let me know by posting a comment if you see this.
