[vsnet-alert 8935] BZ UMa: another short outburst

[Patrick Schmeer]

Visual magnitude estimates by P. Schmeer, Bischmisheim, Germany:
UMABZ 20060619.96  <125 Scp
UMABZ 20060622.943  119 Scp
UMABZ 20060623.939  128 Scp
Instrument: 203-mm SCT
Sequence: AAVSO
 
The current brightening (first noticed by Keith Graham on
June 22.199 UT) has turned out to be another short outburst.
The previous outburst was detected by me on 2005 Dec. 17.895 UT
at mv= 11.6 (vsnet-alert 8776).
The interval of 6 months is close to the mean cycle length of
BZ UMa. (due to the lack of recorded superoutbursts the supercycle
length cannot be determined)

Regards,
Patrick
