it (although I couldn't be entirely sure I wasn't seeing it, either).
However, Rolando Ligustri posted an excellent image to the "Comet-Images"
group that he had taken last night, and armed with that and thus with a
precise knowledge of what to look for, I tried again tonight (20 cm
reflector), and was able to convince myself I was seeing it this time.
Extremely faint and vague -- it was probably easiest to see it by seeing
where it wasn't. Overall surface brightness was perhaps similar to the
faintest regions of IC 405. I'm sure I was only seeing the central regions
of the coma, but overall I was seeing dimenions of approximately 20'
(east-west) by 15' (north-south). By extreme defocusing of field stars, I
measured an approximate m1=7.5:
I probably won't look for this comet again, but I'm glad I was able to get
it this one last time. We've now gone a little over six months since the
