CC Cnc : Superoutburst in November
As reported by M. Simonsen on November 10, the SU UMa-type dwarf
nova CC Cnc experienced a bright (13.2mag) superoutburst
(vsnet-campaign 1221).
The superhump detection by the Kyoto team confirmed its superoutburst
nature
(vsnet-campaign-dn 1889).
Using the 6 nights observations at Kyoto, T. Kato reported the superhump
period of 0.07571(4) d which is 3.0% longer than the orbital period.
Modulations with a period of 2-3 d was also superimposed on the light
curve, suggesting the presence of a beat phenomenon
(vsnet-campaign-dn 1911).
In the data observed by J. Pietz, T. Kato noticed a possible low-amplitude
QPO feature
(vsnet-campaign-dn 1915).
The Kyoto data showed that CC Cnc had undergone a dramatic decline
between Nov. 21 and 22
(vsnet-campaign-dn 1931),
which was confirmed by visual observations
(vsnet-campaign-dn 1934).
