   The object was originally discovered by S. V. Antipin (IBVS 4343) as
a dwarf nova.  An outburst was subsequently detected by M. Iida in 1996
June.  In 1997 May, T. Vanmunster detected a bright outburst (mag 14.1,
CVC 137, vsnet-alert 887).  CCD observations by R. Novak revealed the
existence of superhumps (vsnet-alert 892), confirming the SU UMa-type
nature of the object.  The present outburst is the first reported one
since the 1996 August normal outburst (Jensen).
