I wanted to show some visitors a supernovae, so I went
ahead and obtained a BVRI single-night field photometry
file for the SNIa SN2001bg. You can find the photometry at
http://ftp.nofs.navy.mil/pub/outgoing/aah/sequence/sn2001bg.dat
Nice small galaxy with a lot of structure, which means getting
good photometry of the supernovae is that much more difficult.
Anything brighter than V=14 in the file is saturated and
should be used with caution. As typical with my photometry,
I estimate single-night zero point errors to be around 0.02mag.
