Special Notice #367: Outburst of the UGWZ star UZ Bootis
July 26, 2013
Carey Chiselbrook (CCY; Georgia, United States) reports via the AAVSO Forums that the WZ Sge-type variable UZ Bootis is in outburst. It was observed visually at magnitude 12.8 on 2013 Jul 26 02:00 UT (JD 2456499.58194). The outburst was confirmed by Walter MacDonald (MDW; Ontario, Canada) imaged the field and found UZ Boo at V=12.69 03:25 UT (JD 2456499.6394). Observations of UZ Bootis -- both visual estimates and CCD time series -- are encouraged throughout the outburst.
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:
Special Notice #225: A new UGWZ candidate in Pisces
December 1, 2010: A bright transient in Pisces was discovered by K. Itagaki at an unfiltered magnitude of 12.3 on 2010 November 30.50663 UT (JD 2455531.00663; reported by H. Yamaoka in vsnet-outburst 11854). The object was confirmed at V=12.1 by A. Oksanen (Muurame, Finland) shortly afterward (vsnet-outburst 11855), and I. Miller (Swansea, Wales, UK) reported the presence of superhumps with period 0.0571 day (reported by T. Kato, vsnet-outburst 11859). As noted by Yamaoka and by R.
Special Notice #218: Outburst of the UGWZ star SDSS J080434.20+510349.2
September 21, 2010: As announced by Hiroyuki Maehara in vsnet-outburst 11547, the WZ Sge-type dwarf nova SDSS J080434.20+510349.2 is in outburst, and is also showing evidence of superhumps (vsnet-outburst 11551). Both visual and CCD observations -- including CCD time-series observations -- of this outburst are encouraged. The most recently posted visual observation by Patrick Schmeer (vsnet-outburst 11556) indicates the star is currently around m(vis) = 12.7.
