[vsnet-chat 1683] BZ UMa

Based on the AAVSO alerts, it looks like Watanabe-san's prediction
of an outburst for this star was right on target!

My CCD photometry from the (very) marginal night of 990310 gives
it a magnitude/color of
      HJD       V     B-V    verr  bverr
   51247.8242 11.541 -0.111  0.03  0.02
which is down from its peak of about 10.5, but still bright.

Patrick Schmeer asked me to get photometry of some brighter comparison
stars than given in my Paper II table.  I've posted on our anon ftp
site a file of these brighter comparison stars.  Since the night was
pretty poor, I'd give these stars +/- 0.03mag errors until I can get
a second measure of the field.
