Re: 73P Still Evolving?
- Thanks Maik. This is interesting and something I had not seen. I
try to make sure when imaging that some short exposures are taken
which might help detect any new fragments of any comet being imaged.
It is a bit surprising to me how often these come apart such as
C/2005 K2 not that long ago.
Thanks, Mike H.
