A finding chart and photometric sequence based on one night with lots
of Landolt standards is to be found at

http://vsnet.astro.washington.edu/kevin/apo.html

You may forward the photometric sequence to VSNET if you wish, providing
you mention that realistic uncertainties on the mags and colors are
+/- 0.02 or more.

The reason I have no V-I color for star 2 is that I had a whopping spike
at that location in the I frame.

So far for the SN I get:

    JD         V      +/-    B-V    +/-     V-R    +/-     V-I    +/-
  
  658.6877   17.243  0.002   0.778  0.004   0.004  0.003  -0.218  0.007
  660.6091   17.383  0.006   0.884  0.014   0.042  0.008  -0.167  0.008 

where the uncertainties are internal errors.

I got some IR data on April 26th UT but it wasn't so good.  Just barely
detected it in J and H.  Mag about 18.4 in both filters.
