AAVSO ALERT NOTICE 165 (October 26, 1992)
RARE OUTBURST OF 0846+58 BZ URSAE MAJORIS
Special Notice #390: New possible WZ Sge variable ASASSN-14jv
November 10, 2014: Astronomer's Telegram (ATel) #6676 (B.J. Shappee et al. 2014) notes the discovery of ASASSN-14jv, a bright optical transient found at V=11.3 on 2014 November 9.19 (JD 2456970.69). This object is suspected to be a cataclysmic variable of the WZ Sge subtype. Shappee et al. note that the source is less than one arcsecond away from a g=19.1 magnitude source in the Kepler Input Catalog, suggesting a large amplitude typical of UGWZ stars.
Special Notice #14: BZ UMa Outburst
June 22, 2006: Based on the following observations, BZ UMa appears to be in outburst:
JUN 22.1986 V 11.36 +/- 0.02 GKA
JUN 22.8854 Unf. 11.5 (rough) VMT
Thanks to Keith Graham (GKA) for discovering the outburst, Tonny Vanmunster (VMT) for confirming it and Eddy Muyllaert (MUY) for bringing it to our attention.
Special Notice #377: Reported outburst of the WZ Sge star AL Comae
December 6, 2013: Observer Carlo Gualdoni reports via the cvnet-outburst mailing list that the WZ Sge-type dwarf nova AL Comae is in outburst, with a magnitude of V=12.74 on 2013 December 6.185 (JD 2456633.1185). Gary Poyner notes on the BAAVSS mailing list that this is the first observed outburst of AL Com since October 2007. Both visual observations and CCD time series are encouraged.
