CCD image during the outburst of CP DRa. The image was taken at the
Kyoto University.
While the early phase observations showed relatively short superhump period of 0.0687 day (by T. Vanmunster; vsnet-campaign 793) and 0.078 day (by the Kyoto team; vsnet-campaign 794), T. Vanmunster and M. Uemura later reported 0.08473 day and 0.08491 day, respectively, using combined data sets (vsnet-campaign 803, vsnet-campaign-dn 555). M. Uemura also reported the object was 0.2mag brightening between February 24 (the first observation at Kyoto) and 25 (vsnet-campaign-dn 555). In the late phase of the outbust, the data taken by the VSNET collaboration team showed 0.08348 (5) day periodicity, which implies the decreasing of the superhump period. Their observation on March 6 revealed the outburst entered a rapid fading phase (vsnet-campaign-dn 577).
