Your comet appeared quite green in my shots but I haven't seen any other RGB images of it. I realise that what they are talking about is a much stricter measure but it must be fairly gaseous at least??? Certainly not what I'd expect a dusty comet would show like anyway...
Coming up to a very interesting time now as it hits the SOHO fields.
EDIT: Just bye-the-bye, some reprocesses from 02 Dec images.
First, a video animation:

A composite, after cloning out interfering stars to get a comet-head stack, then layering it over a star stack:

Finally, a new image - forgot that I took 4 subs @ 1-min before I moved onto the two minute exposures.
