Hello again
I have just picked this post up on another forum.
It appears that a SN occurred in NGC 4038 and was discovered in Dec 2007. Rob Gendler hadnt realised he caught it either and he imaged this galaxy in Mar 08, and I imaged it in Apr 08.
I have marked the SN on my image here:

and you can read all about the SNR on Rob's website here.
