OK - I have derived the V magnitude and colors of the star now labeled
number 6 on my chart at

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

That star, just north of the galaxy, is a better one to use than
numbers 4 and 5 (which are further away and more likely to be off the
chip).  

For number 6 I get (with internal errors)

  V      +/-    B-V     +/-     V-R    +/-     V-I   +/-

12.796  0.004   0.672  0.011   0.430  0.005   0.783  0.004

Yesterday morning I got some good frames on 2000cx.  This SN was
really found before maximum.  You recall that I measured it at V = 14.00
and 13.82 on July 19 and 20 UT.  Yesterday (July 27 UT) it was

    JD        V      +/-    B-V           V-R            V-I

 752.8828   13.279  0.004   0.146  0.009  -0.126  0.005  -0.414  0.006


How curious that the B-V color is not changing.  There is a chance
I can get IR data on it this Sunday morning with APO.

(Brian - please derive the coords of star 6.  Thanks.)
