I got another run last night (Sep 19/20), that shows two interesting
facts : (1) the superhumps are still there (usual period, but low
amplitude), (2) the object was fading rapidly (approx. 0.1 mag in
1 hour) and a quick inspection of tonight's CCD data shows that the 
object is indeed returning to quiesence now ...
