"wave" distortion patterns in Cassini ring images

have to sort through, clean up, and post online, I'm going to start
doing some of my own image analysis and see what comes up. I'm more
interested in the white stuff poking through, especially if it's still
there on the next pass. Alex, are your contacts saying anything about
whether this is just cloud formation, or possibly something sticking
up through the haze enough to stand out in the IR?

If you're referring to the high albedo feature over Titan's south polar
regions, then almost everyone I know is fairly confident this represents
tropospheric clouds, especially since the feature is seen to move in the
ISS imagery, and most probably methane condensing out of the atmosphere.

I know a couple of guys named Wheeler and Guth who beg to disagree.

That's interesting. I hope Huygens get some shots of clouds as it
descends toward the surface.

Titanic Man-Of-War floating in the methane sea, with its tendrils
searching for the Methane Muskies, not doubt.

They're up here now:

Thanks

Are the dark markings the hypothesized seas?

I doubt it - they look like atmospheric features to me. I suspect we
are seeing cloud features in Titan's upper atmosphere, unless they are
looking in the atmospheric window.

Apparently scientists are somewhat baffled by what appears to be a lack
of liquid at Titan's surface...

This is probably a silly question, but what are the scattered points of light?
All I can think is "stars", but that's so obviously wrong.

Ok, I had another thought. Blips in the data?

Hmm. I'm not sure what you are referring to. Can you point to a
specific image?
