Well, the fall sequence of targeted encounters is over. But it appears the Christmas flyby includes a great encounter with Telesto (19,000 km) - I hope it is taken advantage of. Also, there is a pretty good Enceladus NT, which, although observations were not originally scheduled, there has been rumor that the last orbit's discoveries have changed that. Does anyone have any info on the Rev019 NTs?

The closest approach distances to some of the satellites:

Mimas 410,000 km - phase 151°
Enceladus 94,000 km - phase 131°
Tethys 175,000 km - phase 114°
Dione 150,000 km - phase 101°
Rhea 201,000 km, phase 104°
Hyperion 225,000 km - phase 60°
Epimetheus 205,000 km - phase 147°
Prometheus 137,000 km - phase 106°
Pandora 225,000 km - phase 161°
Telesto 20,000 km - phase 80°

I don't know which ones will be observed but there are lots of opportunities for NT-observations here.

Quite a few opportunities indeed, including a ~1.5 km/pixel look at Odysseus on Tethys, ~1.5 km/pixel look at the anti-Saturnian and trailing hemispheres of Rhea, a ~2.5 km/pixel view of the leading hemisphere of Dione, another Telesto pass, and a ~4.5 km/pixel view of Hyperion.

High albedo is good, but high phase is even better! biggrin.gif

Also, check out the neat mutual event between Mimas and Enceladus (I guess).
A bit overexposed, though...

Very nice, but as you say, a bit overexposed. I wonder if any of the image-savvy members can make this more better...? rolleyes.gif

I had a look at it in Photoshop and it is actually bleached out there, there's nothing to be had.

Yeah, looks like a classic case of exposure being optimized for ring imaging and not the moons. Why they were using it and targetting Mimas at the same time is beyond me...

Talk about a great orbit. The pic compliments Last months Rhea flyby.

Anybody know what that other moon passing beneath Janus is in my animation? I tried identifying it with Celestia, but I was unable to... I'm guessing either Epimetheus, Prometheus, or Pandora.
