Nice movie! It's designed to show the terminator crossing the Amata structure in the middle of the grooved terrain.

Wow, very nice!

Nice one Mike! wink.gif

It's prompted me to put together this more 'arty' GIF animation, showing a bright object passing through the NAC's field of view:

Titan behind the rings, October 4, 2011:



(This really shows off the asymmetry of the two hemispheres, the North Polar Hood is there, but there's no south polar hood, and the two hemispheres are evenly lit.)

Images of a Rhea-Titan mutual event are down (see http://saturn.jpl.nasa.gov/photos/raw/?start=1&storedQ=2391276).

Shame there seems to be an occurence of overexposed satellites in the recent mutuals. I would have expected their software to make picking good exposures almost an afterthought given how they must have built a large dataset on each satellite's brightness as a function of phase angle by now.

Posted by: Phil Stooke Oct 5 2011, 05:25 PM

You're right... so probably there's some other purpose behind the longer exposures.

Nice catch by the Cassini team - Epimetheus occulted by Enceladus' North pole:

Great shot. Are we also seeing here some vertical structure in the rings at lower right?

Posted by: ugordan Oct 7 2011, 08:17 PM

If you mean if there's one of those spiral-wound structures noticeable at the ring ansa, it's possible, but the raw jpegs are too thrashed to make it out clearly.

Posted by: ngunn Oct 7 2011, 08:36 PM

I was referring to the bright streak containing three brighter peaks that is very prominent in the middle of the rings, starting roughly below the rightmost limb of Enceladus and extending towards the right.

Posted by: ugordan Oct 7 2011, 08:41 PM

Oh, that. Since it's too far past equinox to show any dramatic ring topography, my WAG would be that's a clump of forward-scattering dust in an otherwise pretty empty region. What is that, anyway - Cassini division?

Posted by: ngunn Oct 7 2011, 09:10 PM

OK, sounds good, but I didn't know there were localised clumps of material like that in the Cassini Division (if that's indeed the location). I was thinking something out-of-plane might appear brighter by being more directly illuminated - maybe a spoke-type feature or moon wake?? It's pretty striking anyhow.

Last remnants of the Serpent Storm doing a little yin yang thing up there?

My guess is that it's clumping caused by either Pan or Daphnis as shown in this shot (which shows brightening caused by both moons)
