[vsnet-campaign 803] Update on CP Dra campaign (CBA)
Dear colleagues,
The CBA campaign on CP Dra is progressing well, with additional
contributions coming from CBA East (Dave Skillman) and Nicolas Copernicus
Observatory (Rudolf Novak). The complete data set very well shows the
transition from initial superhumps at the start of the CP Dra outburst,
(amplitude of about 0.22 mag), to full-developed common superhumps with a
peak-to-peak amplitude of 0.34 mag. The profile of the superhumps is stable
over the entire period, and the same seems to hold for the superhump period,
which - using the PDM method - yields a value of
0.08473 +- 0.00006 d.
We are now observing the fading part of the outburst. This is a rather
interesting phase and we urge observers to continue monitoring the outburst
till the object completely fades from visibility.
With kind regards,
Tonny Vanmunster - CBA Belgium
Brian Martin - CBA Alberta
David Skillman - CBA East
Denis Buczynski - UK
Rudolf Novak - Czech Republic
