The latest shots of Mezzoramia and environs are nice:

Electric Cloud-O-Vision image of N0013574-76 [MT1 = -77]:
(Pseudocolorized areas where polar clouds are brighter than background. Pseudocolor scales to relative cloud brightness; purple=darker clouds/haze, red = brightest cloud/haze) [EDIT: Image details can be found here: http://www.flickr.com/photos/31678681@N07/3487876831/] -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

It's interesting to see just how localised the very brightest colours are there. Would a single active convection cell look like that? I hope we get some follow-up images.

It's interesting to see just how localised the very brightest colours are there. Would a single active convection cell look like that? I'm not sure. The overall brightness in that region might be an artifact of the subtraction process between the ISS (CL1/CB3) and the MT1 image. The overall brightness should be a function of cloud reflection+haze reflection+funky specular components from haze+cloud+atmosphere+surface w/respect to MT1 brightness. To really see how big the bright cloud part is, it would be necessary to normalize out the bright cloud with respect to the bright haze and bright (specular?) atmosphere. That should be doable....later.... -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
