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.
