GO Com: superoutburst continues!

Dear Colleagues,

   The VSNET Collaboration has received new data from Nakajima-san and
Tom Krajci.  The object is still on its plateau stage, and the "rebrightening"
phenomenon is confirmed to be a transient one, rather than triggering
a rapid decline.  The superoutburst now has a duration of 9 d since the
peak magnitude.  The object is about 1 mag fainter than its outburst peak.

   The superhumps are still prominently seen, with somewhat unusual
profiles and a slightly increased amplitude.  The most striking feature
is that the decrease of the superhump period (again!).  The period change
is never monotonous (linear or with a single quadratic term) in GO Com!
The combination of the all above results seems to be understood as
the effect of a beat phenomenon, though this needs to be examined with
the full analysis.  Please keep continuous observing, even if the object
may start fading.

Regards,
Taichi Kato
VSNET Collaboration team
