V632 Cyg: a new SU UMa-type dwarf nova

   As reported in [vsnet-alert 10693], Pavol A. Dubovsky succeeded in
detecting superhumps.  Nakajima-san also succeeded in recording
superhumps.  From these observations, the best superhump period
is 0.06549(13) d, 2.7% longer than the orbital period (0.06377 d,
Sheets et al., PASP 119, 494).  These observations now firmly
established the SU UMa-type nature of this object.
We expect to obtain further observations soon, and will be able to
refine the period and its development.  An SU UMa-type dwarf nova
at this period is expected to show a positive period derivative
and a rebrightening.  Please continue observing!
