“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 ??? |

The stuff about Arrakis Planitia and the October 2004 storm is in a paper now in press over in the journal Icarus:
