Measured ER UMa at 12.9 CV on 2021/12/28 03:08:50 using SLOOH in the Canaries. Hopefully some more results will arrive to refine the timing of what appears to be a superoutburst.
This is only ~45 days after the start of the last one. Most periods lie in the range 45 to 60 days – so quite short. See VSSC188 for a full graph of super cycle period over the last 200 or so cycles for context.
