Yep, I'm confused. I didn't get out with my 12.5" Starmaster 'til just
before 9:00pm, really just to check out Saturn (breathtaking!), but when
I looked over at Jupiter, I thought all four moons were to the west of
the planet, with the two nearest the planet's limb sitting on top of one
another. Jupiter was only about 30-degrees above the horizon at the
time, and I thought there was a relatively bright star just to the east
of Jupiter's limb. After observing Jupiter for a bit, I *thought* I'd
witnessed an occultation of two moons. Was I just seeing stars? (No
pun intended.) I need to bring Jupiter up on _TheSky_ or _Starry_Night_
to figure out what it was I was seeing.

Saturn was just magnificent last night, as was the seeing. (Thanks for
the heads-up, Phil!) Probably the best I've ever seen it from San Jose
... in a non-AP 'scope, that is. Just blew my neighbors away, too. If
the seeing tonight is as good as it was last night, be sure to get out
there! In addition to Titan, I think I spotted five moons in Saturn's
immediate vicinity. Time to do my homework to figure out if some of
these were actually stars.
