From the Looking Ahead entry "This [ISS] mosaic, HIRESNA001, will focus on a region near 65 degrees south latitude, 260 degrees west longitude. Several dark features have been previously observed in this region, though these features do not have a low enough albedo to be considered lake feature candidates. Their current origin is unknown"

Cool! This is an area to the SW of the T53 Mosaic.

The red plus sign shows the approximate center of the focus area in relation to the T53 Mosaic and the global map.

Personally I have never been able to get excited about Cassini's images of Titan. They alwasy seem so fuzzy. Maybe some artist's interpreatations might be better ? I loved the Hugans images though.

Here's another view of the southern hemisphere, with Elba Facula standing out like a sore thumb:

Mezzoramia can also be seen near the terminator.

Animated sequence of a stellar occultation of Titan's haze layers by a bright star:

(click to animate)

The CL1/VIO filtered Wide angle camera images were placed in the blue channel.
The CL1/VIO filtered Wide angle camera images were placed in the red and green channels.

The images were realigned to show the shortest path of the star through the atmospheric layers.

A static image showing contrast-enhanced zoom of the atmospheric layers as the star sets can be found here: http://www.flickr.com/photos/31678681@N07/3516686323/

(the animated GIF is also in my photostream).

I wonder what's providing the backlighting there. Hyperion? Iapetus? Just starlight?

I'd guess the rings; they're not completely edge-on yet.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

I presume that's what's providing the front lighting.

Could be the rings, but indirectly. They're almost edge-on as seen from Titan and probably not very bright in high phase geometry. It might be ringshine onto Saturn's nightside which in turn illuminated Titan.
