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.

Special Notice #261: Outburst of the UGWZ Candidate BW Scl

October 21, 2011: The short period cataclysmic variable BW Scl appears to be in outburst. The object was detected in outburst at m(vis)=9.6 by M. Linnolt on 2011 October 21.3146 (JD 2455855.8146), and confirmed by A. Plummer at m(vis)=9.4 on October 21.3424.  Observations of this object are encouraged.  The object has conflicting classifications in astronomical literature, but is probably a WZ Sge-type dwarf nova rather than a novalike variable.

BW Scl is located at the following (J2000) coordinates:
