[Aavso-photometry] BZ UMa Update

[Aaron Price]

David Boyd has confirmed the outburst at V=11.6. Tonny is currently
getting some observations but weather is threatening to shut him down.

Europeans: Please kick in for the next few hours to cover the daylight
in North America.
North Americans: Please prepare to get on it as soon as you can and
please observe as long into the night as possible.
Pacific & East Asians: You have time to rest, but please start as
early as you can this evening. There is normally a Pacific gap so lets
do what we can to minimize it this time.

BZ UMa's outbursts are usually short (~5 days) so rest assured I won't
be bothering you all for observations all week long. See what you can
do!

I have created a web page clearinghouse for data and updates. It is
crude now but our most excellent webmaster will surely improve it
tomorrow. It is here:
                                         http://www.aavso.org/news/bzuma2.shtml

In the last outburst a quasiperiodic oscillations appeared around many
frequencies, the strongest and most persistent being 0.068 ± 0.002
days, 0.065+/- 0.003 days and  0.030 ± 0.0004 days.  In our April,
2004 quiescent campaign a really interesting dual peaked superflare
was detected with an amplitude of around 0.8 mag and duration of
around 30 minutes plus there was lots of interesting quasiperiodic
behavior.

Lots of fun stuff to look for! Please keep your observations as clean
as possible. The decline will be rapid and our last campaign data was
a little noisy. If you need to expose for 5 minutes and/or stack then
please do so.  And post feedback and updates to aavso-photometry.
Let's nail down the type of this star!

Good luck and clear skies!
