[Taichi Kato]

  V632 Cyg sometimes show low-amplitude outbursts.

  I have been suspecting that this object is an SU UMa-type dwarf nova.
Time-resolved photometry during the current outburst is encouraged!

Dear Colleagues,

   We have finished analyzing the Kyoto Dec. 12 observation.  The data seem
to show slow modulations (amplitude ~0.1 mag) with a time-scale of ~2 hr.
The periodicity has not been confirmed because of the temporary intereference
by clouds.  This modulation could be a hint of emerging superhumps; since
the present outburst is a long, bright one rarely seen in recent years,
further intensive observations are strongly encouraged.
