[vsnet-alert 7327] GP Com possible outburst !!??



GP Com possible outburst !!??

   Pavol A. Dubovsky also reports that GP Com (helium cataclysmic variable,
presumed to be analogous to WZ Sge-type stars in hydrogen-rich systems,
is apparently undergoing an outburst (first ever!).

COMGP 020507.9479  14.7  DPV   14.40-2V1-14.89               

   Confirmatory observations are most uegently requested, as well as
time-resolved photometry and spectroscopy to detect any short-term
modulations!  The orbital period is only 0.0323 d and you absolutely
need intensive and dense sampling!

   This star, if the outburst is confirmed, is the top-priority target
of the VSNET Collaboration team.  If the star is found to be too faint,
please turn your telescope to IY UMa.

   When you send raw data, please remind to send them also to Uemura-san and
Ishioka-san, uemura@kusastro.kyoto-u.ac.jp and ishioka@kusastro.kyoto-u.ac.jp)
in order to avoid any delay.

   Good luck to all observers!
