[vsnet-alert 3884] QY Per superoutburst update

QY Per superoutburst update

Dear Colleagues,

   Congratulations to all who detected the outburst, and succeeded in
observation!  Special thanks to all who quickly responded to the alert
and recorded superhumps.  Please continue your nice observations as long as
possible on this rare occasion!

   As for the Kyoto observation, we (T. Kato and M. Uemura) observed QY Per
for 8 hour's nearly continuously last night.  A very preliminary analysis
of the (partly reduced) data has yielded a superhump period of ~0.082 d,
close to the one reported by Gianluca Masi.  The relatively long superhump
period and the rare outburst occurence seem to strengthen the relationship
with DV UMa, whose spectacular superoutburst is still fresh in our memory.
We would like to inform more detailed information after finishing the present
reduction and collating incoming information.

   We would like to set up a special page on QY Per, as we have had on
DV UMa.  We would be extremely happy to receive the data to be reflected
to the Web page (Y2K and time permitting...).  The data should be sent to
tkato@kusastro.kyoto-u.ac.jp.

   Congratulations and thanks again to all!  We will be having the second-
night run soon after this.

Regards,
Taichi Kato and Makoto Uemura
