[vsnet-obs 1250] Re: V630 Cyg Correction, JLT

   Although V630 Cyg has been a relatively well-known program star among
variable star observers, this dwarf nova is still a "suspected" SU UMa-type
dwarf nova.  Some historical records ...

  max JD     mag   duration

  2437899   15.0   short
    37927   13.8   long (15d), probably a superoutburst
    37968   14.5   short
    38026   14.7
    38260   14.6   short
    38291   14.1   short
    38340   14.8
    38583   14.5

   I would like to call observers' attention to monitor this star for
superoutbursts, in order to confirm the long-suspected classification.
Although outbursts of V630 Cyg are not rare, I think this star still
deserves to be included in the alert program, especially for alerting
superoutbursts.
