I believe you are right about that.  I was going on the idea of bursts of
activity, almost like on/off gases.  Just not so sure yet if that is
correct.  Will have to do more looking around at actual photos.

Povray ?

Cloud image mapped onto a slightly larger sphere than the Earth surface one.
Not a greatly detailed one but it's better than trying to make that at the
same time as dealing with the comet creation.
For planetary maps have a look at this site:
