ER Uma approaching superoutburst

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

Stewart John Bean

In the next two weeks ER Uma will probably start a new superoutburst. This is based upon a superoutburst period of 55+/-5 days.

A graph of the superoutburst period against supercycle number is further up the thread – which shows this star “wanders” around 50 or 55 days for the super cycle period. 

ER Uma is a good target in the spring. Observations are encouraged.
