[vsnet-campaign-sn2002ap 7] SN 2002ap

["Berto Monard" <LAGMonar@csir.co.za>]

There is a one night photometry on NGC 628 from A Henden on his
'sequence treasures' site,  V magnitudes only and R-I differentials
(possibly unrelated values??). 
I would be surprised if the bright stars were not saturated. 

Surely Arne will want to follow up on his measures tonight (heavens
allowing) and present them in due time with proper colour indicators.

We can off course compare the present data with B-R magnitudes from U2
to sort out the blue stars in the field.

I suggest Tycho II magnitudes if SNap would be of type Ia, in which
case
it ought to brighten below magnitude 12!

  Does anyone have a well-calibrated photometric sequence around this
galaxy?
