As mentioned by Jeremy in VSSC 190 (the latest) several ER UMa stars are due a superoutburst before the year end. With a disclaimer on the accuracy of the dates, I copy below my expectations for four stars.
Superoutburst period (d) Next superoutburst (give or take a few days)
RZ LMi 25 Dec 11 Late evenings
V1159 Ori ~50 Dec 22 A late evening target
IX Dra 60 Dec 30 An early evening target
ER Uma 50-55 Dec 30 – Jan 2 Late evening target
