SW Ursae Majoris is a dwarf nova of the SU UMa subclass.

SW UMa was observed in Ostrowik during 9 nights in the spring of 1996. The results of this campaign were described in one paper published in Acta Astronomica.

Abstract:

We present CCD R photometry of SW Ursae Majoris -- an SU UMa type cataclysmic variable -- obtained during its April 1996 superoutburst. The mean value of the superhump period P_sh derived from our observations is 0.05818 +/- 2 days (83.8 min). The analysis of times of superhump maxima gives clear evidence for the increase of the superhump period with dP_sh/dt=8.9 times 10^-5
