Special Notice #43: Possible Super Outburst of BZ UMa

April 14, 2007

The cataclysmic variable star BZ UMa is currently experiencing an outburst which is peculiar for that star. Historically, BZ UMa has outbursts every 312 +/-114 days (although it has been much more regular in the past decade). These outbursts are similar to regular UGSU outbursts with a fast rise and a short decay over four days and are absent of any superhumps or other periodicity. However, no superoutbursts of the type also associated with UGSU stars have been detected in BZ UMa despite good observational coverage since 1972.
