   Gene Hanson (USA) reports in [vsnet-obs 5792] a rare outburst of the
SU UMa-type dwarf nova V1028 Cyg.

   The latest outburst of V1028 Cyg occurred on 1996 Aug. 7, when J. Pietz
detected the star still rising to maximum.  After attaining the maximum
of mv=13.5 on Aug. 8, the star started to fade rapidly.  Preceded by this
short outburst, the star rose up again on Aug. 11, and entered a stage of
11-day lasting superoutbust.

   The 1995 July to August superoutburst was quite intensively studied by
the Ouda team (Kyoto University), first revealing this object to be an
SU UMa-type dwarf nova phenomenologically bridging the usual SU UMa-type
and WZ Sge-type dwarf novae.  A more detailed discussion is given in Baba
et al. (1997, PASJ submitted).
