[vsnet-alert 5057] BF Ara bright outburst

BF Ara bright outburst

   The dwarf nova BF Ara is reported to be undergoing a long, bright
outburst.  At least one report (IBVS 2286) reported the possible presence
of a superhump.  The interval of outbursts as short as 7 d is also
rather exceptional for an SS Cyg-type star.  Since BF Ara had a bright
outburst in April, this star, if confirmed to be an SU UMa-type dwarf nova,
may be the first southern ER UMa star.

   Observations are strongly encouraged.  The object is also a timely
vsnet-campaign target.
