Variable Star BZ UMa
Outburst of BZ UMa (25 February 2004)
BZ UMa was discovered by Markaryan (Astrofizika 4, 144) on one of his 
objective prism plates. The star was bright (10.5mag pg) on one exposure and faint
(16mag) at other dates. One further maximum (11.0mag vis.) has been observed since,by members of the AAVSO (Mayall, Journ. R. Astr. Soc. Canada 66, 181).IBVS 2256

 
 
Outburst report was by  Michael Simonsen,  (MI. USA) mag 11.6 on 2004 Feb 25.29. According to the AAVSO International Database, BZ UMa appears to be in outburst, its first since December,2002.
BZ UMa is classified as a UG by the GCVS. However, it is suggested to be a SU UMa subtype due to its short orbital period and mass ratio (Jurcevic et. al. PASP 05/1994). According to W. WENZEL , BZ UMa might be an intermediate object in connecting the U Gem and WZ Sge classes. (IBVS 2256)
