[vsnet-campaign 558] DO Dra (YY Dra) outburst

DO Dra (YY Dra) outburst

Dear Colleagues,

    As reported by Christopher Jones, Patrick Schmeer and other observers,
the intermediate polar with rare dwarf nova-type(-like?) outbursts
is undergoing a major outburst.
    During the previous outbrust (1999 September), the Kyoto team obtained
a successful time-series using 10-15s integration times.  On other
occasion in outburst, the system showed qsasi-periodic modulation
whose period didn't seem to be directly correlated with the reported
spin period.  Anyway, previous photometry during outburst of DO Dra
showed relatively strong short-term variation, which is rather unlike
usual dwarf nova-type outburst.
   As has been always recommended on every outburst occasion, time-resolved
photometry is strongly encouraged.  Please use short integration times.

   Follow-up information will be provided in vsnet-campaign-ip.
