“On December 5, ISS will image a half-phase Titan at a distance of 2.5 million kilometers (1.55 million miles). The camera will image the sub-Saturn hemisphere of the satellite, allowing researchers to continue to study the recent weather changes that have been occurring across Titan's equatorial region and that have brought methane rain to select regions of previously dry terrain”.
Seems a shame the NAC or WAC couldn’t take a few images before Dec 5th say on the second. Based on the SSS it would seem the area in S Senkyo (around 310 W and -20 ) that almost certainly had intense precipitation is better seen on the 2nd below left, and may be beyond the terminator and invisible on the 5th below on right. Also I couldn't confirm with the SSS that Titan would be as close as 2.5 Mkm on the 5th ??? |

Grr, no I goofed. I had Enceladus still selected in Celestia and didn't notice that when I wrote down the distance. Let me get a corrected number.
Yep, that should be 3.42 million kilometers. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

The distance has been corrected in the Looking Ahead article. Thanks for the catch, titanicrivers.

Some Dec 5th images are in the raws but I really couldn't spot any obvious clouds nor surface features changes that suggest localized flooding. Anyone else see changes? I'll have to work more with the images as initially there seem to be an enhanced channel on one of the CL1 CB3 images.

Here's a possible surface change in the S Senkyo region (between -10 and -20 latitude and 320W and 330W) present on the Dec 20 CL1CB3 filtered images. The dark area (arrow) seems fairly prominent now compared to pre- T72 storm images of the same area. Haven't gone through all previous images and the lighting and processing of the images differs but the change is similar to S Polar ISS images following the 2004 storm.

Wow. You've made quite a convincing case there.
I would really love to hear what the professionals think about this. Have they noticed it? -------------------- -- Hungry4info (Sirius_Alpha)

I can neither confirm or deny anything you have experienced with these images. Next question please.

at a quick glance it dose not appear that there is a change , other than rotation .
QUOTE I can neither confirm or deny anything you have experienced with these images. Next question please a nice bit there . |

Now that's much more compelling evidence. Nice work.
