CC Scl: superhumps and strong spin modulation

   Berto Monard and Josch Hamnsch have reported observations.
The object shows superhumps, but the amplitude is already
low.  A more striking feature is the presence of strong
spin modulations (0.08 mag), which can be directly seen
in the light curve.  The period is 0.0045094(3) d = 389.61 s.
This object is the first SU UMa-type dwarf nova whose
IP pulse is clearly visible during its superoutburst.
