[vsnet-campaign-dn 2802] KV Dra: superhump period increased

KV Dra: superhump period increased

    We have received a new data from J. Pietz.  New CCD images taken
by K. Tanabe and the Kyoto team have been also reduced.  The combined
light curve now includes over 3000 photometric points.  Our period
analysis shows an average superhump period of 0.060005(17) d, which is
slightly longer than those reported in September 1-3.  Amplitudes of
superhumps are still small (0.1-0.15mag).  The decline rate, which
became more gradual on September 3, is now again faster at 0.2mag/d. 

Regards,
Makoto Uemura
