[vsnet-alert 2612] Superhumps in CY UMa confirmed



Superhumps in CY UMa confirmed

Dear Colleagues,

    A time-series CCD photometry on Feb. 12 (Ouda team rooftop station,
25-cm SCT + ST-7 unfiltered) has revealed the presence of large-amplitude
superhumps (amplitude = 0.33 mag) in CY UMa.  The persent observations
confirmed the superoutburst nature.  There is an indication of superimposed
QPOs (amplitude ~ 0.10 mag) during the decline branch from superhump maxima.

Regards,
Taichi Kato
