ASASSN-15sc: stage A-B superhumps?

    Tonny Vanmunster, Kasai-san, Maeda-san, Ian Miller
and Javier Ruiz have reported observations.
Superhumps were detected since October 31
(no observations have been reported on October 30).
Tonny's initial superhump detection probably referred
to (the final phase of) stage A superhumps.
The current superhump period is shorter.
