New Titan Image: Monitoring Fensal-Aztlan


CICLOPS has released this mosaic of the Fensal-Aztlan (formerly known as the "H") region on Titan. Fensal is the northern branch of the "H". Fensal has some subtle brightness variations and has quite a few bright spots, or "islands", dotting the region. Their distribution appears to be more scattered than similar sized bright spots in Shangri-la, west of Xanadu. There, the spots were clustered into several "archipelagoes" and aligned in a similar fashion, usually east-west. The spots in Fensal don't seem to have a prefered orientation. A few larger bright spots can be seen in Fensal, including Bazaruto Facula on its eastern end.

Aztlan, the southern branch of the H plus the dark region surrounding Elba Facula to the east (not in this particular crop), has far fewer smaller islands, but does have several large islands, including Sotra Facula, a 240 by 120 km sized bright feature just right of center in the lower left frame, and Coats Facula, a smaller island to the east of Sotra.

This mosaic is just 4 frames within a larger, 20-frame mosaic to be released later. This mosaic was taken during last week's T7 encounter.

I was compelled to think about outgassing as well when I first saw the images of the area. It seems, however, that it's a pretty permanent feature, most likely a gradual change in albedo, maybe windblown surface organics?

I am actually working on those two features for a paper :-)
