[vsnet-alert 333] Re: BZ UMa in outburst.

   There is a very good article by Jurcevic et al. (1994, PASP, 106, 481)
treating of the long term behavior of BZ UMa.  The present reported value
may be within its "usual" quiescent range of 15-16 mag (or maybe slightly
above its upper limit depending on the exact value).  The extreme value of
17.8 mag was only once recorded by Kaluzny (1986, IAU Circ. No. 4287),
which might still need confirmation.  I also think there is a good chance
that BZ UMa may be experiencing its early rise to a outburst.  Close
follow-up observations would reveal the truth.

   In 1994 October (just the moment when the star was in outburst) we had
a discussion concerning the "peculiarity" of BZ UMa, and what the word
"peculiar" means in CVs.  I have just dug out the corresponding articles
from the VSNET log where they have been buried.  Since they are too lengthy
to be posted here, I will soon make them available through the VSNET Home
Page (http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/).
