“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 ???

Here is another pair to ponder. The raw images are a closer match as far as distance to Titan and longitudinal center of the image. Arrow points to possible albedo difference. Images rotated so N is up and slightly enhanced.

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

I appreciate your comment ugordan! Hopefully the observation will hold up under closer scrutiny.

I took the two observations you mentioned - the 2009 one is available at the PDS - and made a flicker gif. CB3 stacked images divided by a MT1 frame in both cases. 50% original resolution, though not much detail is lost due to atmospheric scattering.

I don't know how many of the other subtle albedo changes are due to haze differences (whether in MT1 or closer to the ground in CB3 frames), but the Senkyo change is indeed compelling.
