Its interesting to compare these latest photos with ones recorded by the VIMS instrument and reported at the LPS 2008. The giant polar ethane cloud covered the pole out to 64 degrees N latitude. The edges of the denser cloud bands of the April 29, 2009 photo (using Phils neat enhanced image) appear to have a similar distribution. Question: are clouds seen by ISS CL1 CB3 filter in the north different from the VIMS polar cloud? Can we still infer that the giant polar cloud is still present?
