Scientific paper

We present more than 30 years of outburst data on the dwarf novae VW Hyi and Z Cha from visual observations made by southern hemisphere amateurs. We study the statistical properties of the outburst durations, quiescence intervals, and cycle times. We compare correlations between these timescales for VW Hyi and Z Cha with the results for SS Cyg obtained by Cannizzo & Mattei (1992). Z Cha proves to be too faint for a complete analysis. VW Hyi, however, shows a richness of variations comparable to SS Cyg. No apparent differences between VW Hyi and SS Cyg can be attributed solely to the SU UMa phenomenon.
