Key Quote: "The Sotra area thus seems to be a leading candidate for a cryovolcanic field on Titan. "

AGU abstract for Randy Kirk's presentation on Tuesday:

(Serious bonus points for bilingual word play in the title: "La Sotra y las otras")

It is an overlap of T25 and T28 RADAR Swaths. T25 has the better Sotra Facula image.
T25: <a href="http://photojournal.jpl.nasa.gov/catalog/PIA09182" target="_blank">http://photojournal.jpl.nasa.gov/catalog/PIA09182</a>
T28: http://photojournal.jpl.nasa.gov/catalog/PIA09217

T25 was taken February 22, 2007
T28 was taken April 10, 2007

15 degrees south latitude, 40 degrees west longitude. So, it must be in the optical "H" of Fensal/Aztlan and more precisely in the optically-dark Aztlan. An irregular bright patch in Aztlan! Correct?
Have you precisely spotted Sotra Facula in the radar swaths ?

VIMS data tend to suggest multiple candidates for cryovolcanic activities, now: Sotra Facula, Hotei Arcus and the other "roughly" circular areas with a dark central feature (calderas or impact craters?). With more lucidity (or imagination),we may find the "Big One".

Sotra Facula, maybe a good place in the next centuries or millenia to go skiing (1000 meters or 600 miles tall). blink.gif

Yes, its been clearly identified in radar swaths T 25 and T 28 (see Juramike's post #6 above). Go to VP's Swath's website http://pirlwww.lpl.arizona.edu/~perry/RADAR/
and look for it in T25 part 1 where it has its best appearance. Juramike identified this as a volcano candidate quite a while ago! The graphic below shows Sotra Facula in the T 25 part 1 swath. The final frames of the animation use a color scheme from the Planetary Photojournal movie delineating the dunes and cryolava geological units. http://photojournal.jpl.nasa.gov/catalog/PIA13695
