CC Cnc superhump period update

Dear Colleagues,

    Based on preliminary analysis of 6 night observations, we have obtained
the superhump period of 0.07571(4) d.  This value is 3.0% longer than
the orbital period (Thorstensen et al.).  This superhump excess also
precludes the former possibility that CC Cnc has an anomalously large
excess.  Modulations with a period of 2-3 d is also superimposed on the
light curve, suggesting the presence of a beat phenomenon.  This system
may thus have a rather high inclination, although the spectroscopic
solution may not by strongly indicative of that.

    We now have a long baseline enough to determine the period change.
Further observations are encouraged.

Regards,
