Dear colleagues, aprox. 4.8 hours long run on BZ UMa in R-band Kroun-Cousins filter using SBIG ST-7 and 0.4m Newtonian telescope shows rapid decline form current outburst which seems to be a normal one. The rate of decline is aproximately 0.66 mag / day. The limit of possible fast variability was equal to 0.05mag and there is no flickering up to this limit. this mean it's impossible to be an SU UMa type variable in superoutburst. Let's observe some different one :) Regards Rudolf Novak N. Copernicus Observatory Brno
