Re: Bright object in southern sky
If you look at Jupiter with decent binoculars, or a spotting scope, you can make out 3 or 4 moons depending upon where they are in their orbits. Sometimes one is in front of, or behind, the planet and indiscernable They have brief orbital periods, so you can see the position of the moons change from nite to nite. Make a sketch of what you see one night, then look again a few nites later, make another sketch and then compare the two.
The readily visible moons are Io, Europa, Calisto and Ganymede.
I think this is my post #1000. I need therapy.
