Hello,
   yes I would be pleased to help solving this.

   I have a good idea ( I hope ) and that is that David Bishop add two lines
   at the top of  the Supernova webb pages which say :

  "Please use comparison stars indicated on this picture for magnitude
estimates :"
http://vsnet.geocities.com/SiliconValley/Garage/9531/ngc2320a.jpg

I used the formula 0.375*Bmag + 0.625*Rmag ( USNO-A1.0)

If this is a good idea, I can make a reference picture for all the Bright
Supernovae
shown on David Bishop's webb pages.

Yours sincerely
Odd Trondal
