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 Psh 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 dPsh/dt=8.9 times 10-5
