E. O. Waagen, AAVSO, reports that the cataclysmic variable SW UMa is in superoutburst for the first time since Oct. 2002, when the star reached visual mag 10.5 and was brighter than mag 13.5 for 17 days (the normal minimum visual mag being approximately 17). Visual magnitudes reported to the AAVSO: Aug. 21.876, [13.5 (D. Naillon, Lithons, France); Sept. 12.140, [13.0 (P. Schmeer, Bischmisheim, Germany); 13.149, 10.8 (Schmeer); 14.036, 10.2 (S. Swierczynski, Dobczyce, Poland); 14.138, 10.4 (Schmeer); 14.172, 10.4 (Schmeer); 15.024, 10.1 (Swierczynski). Waagen adds that the outburst frequency of SW UMa varies a lot, from less than a year to as long as 5 years, as does the pattern of normal outbursts versus superoutbursts; prior to the 2002 outburst, there had been an outburst only 15 months previously.
