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
