Rev 141: Titan, distant view after the storm Options

[titanicrivers]

“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 ???

To quote VP in post #34 above ... 'but one likely one is that the rains have cleaned off "gunk" off portions of Titan's surface, revealing brighter material beneath the...ummm....gunk' ...

The S Senkyo area may be a good example of what VP is suggesting. A S Senkyo topography map (color swaths from Zebker and Stiles et al http://www.sciencemag.org/content/324/5929/921.full), while far from complete did interestingly enough include a swath near the area of bright and dark change as seen in the Dec 20th ISS image. There's a slight bump in part of the bright outer rim suggesting its higher and making a case for a whitening of a topographic high washing darker 'gunk' downslope into a relatively lower basin. The figure below shows the basemap and then Dec 20 image and finally the SAR altimetry swaths. The arrow points at the possible higher terrain. The whole area was directly under the Arrow Storm.
