[vsnet-alert 143] Superoutburst of AL Com terminated?

Dear Colleagues,

Our (Ouda Team) photometric observation revealed that AL Com is
undergoing  the decline by about 1 mag in a day these two days.
The current superoutburst of AL Com really ended up, maybe. However,
AL Com seems to have risen by 0.5 mag in last an hour during our
5.8 hours observation.  The rise may be a part of large amplitude
(~ 0.7 mag) modulations with a period more than 6 hours, or it
may lead to re-brightening again.  Although observations are
thought to be very difficult because of the decline, follow-up
observaiton is highly encouraged.
