[Aavso-photometry] BZ UMa observations at CBA Belgium Observatory - initial results

[Tonny Vanmunster]

Dear colleagues,

I just posted my BZ UMa observations of tonight (2005, Jan 16/17) on my CBA
Belgium Observatory website (www.cbabelgium.com). My observing session
started at 18h01m UT. I used a 0.35-m f/6.3 telescope with ST-7XME CCD
camera and V-filter. Sky conditions were pretty good initially (despite
moonlight), but around 20h08m UT, thick clouds prevented me from further
observing. The initial stage of a BZ UMa outburst is not yet well studied,
so the present observations might still be of interest, despite the short
duration of the session.

The resulting light curve depicts a steady increase in BZ UMa's magnitude
(rising from mag 11.31 to mag 11.20 in 2 hours), but no further obvious
modulations are seen. 

I hope to continue observing BZ UMa over the next nights, although the
weather forecast is not looking positive. Most BZ UMa outbursts are rather
short lived (~5 days), so make this a top priority target !

Best regards,
Tonny
