ISS imaging over N Adiri (Sliced Carrot and the Dancing Monkey)

Ciclops http://ciclops.org/view/6026/Rev122 also mentions improved ISS mapping of western Belet.

Interesting images today:

Impressive detail!

I think those must be in the south polar region seen here:

More great global views with plenty of clouds:

I've just realised what Titan's isolated long parallel cloud streaks remind me of:

Hmm. Starting to rain a bit in the north? (Those clouds are in the north, right?)

Nope, all of these are southern midlatitude clouds at various lats. Though we have seen northern mid-latitudes clouds too, but I guess it was a "sunny" day there over the weekend (as sunny as a smog covered world can get, okay?)

Way cool!

Any chance you could redo the animation with the image center always fixed on the midpoint of the cloud? To my eyes it looks like you can see the clouds shifting around, but it's hard to see combined with the rotation of Titan.

I tried, but Cassini's vantage point makes Titan rotate too much so I just left it this way. To my eye it's clear that the center cloud pattern appears to be racing faster than the moon "rotates".

Well, if you can be patient, that's one of my tasks for the week smile.gif

As per VP above, these are mid-southern latitude clouds. Using the ISS figure in Ciclops, a celestia grid and NAC image N00148413 one can approximate their location as shown below:
