March superoutburst and superhumps

Forums Variable Stars ER Uma and RZ Lmi: Observations requested. March superoutburst and superhumps

Stewart John Bean

James DeYoung (USA) has uploaded three days of results –  including superhumps  starting at JD 2459285.5. So the outburst seems to have started at JD 2459285 giving a superoutburst period of 55.3 days since the last. This compares to 54.7 days for the previous period. So 55 days seems a good number to use for the next outburst although there may be an increasing trend as shown in the graph.

The next superoutburst may be around May 5th  give or take a week.
