BF Ara: Candidate of the first southern ER UMa-type dwarf nova ?

A bright long outburst in June - July

The dwarf nova BF Ara is reported to be in a bright outburst (14.2mag) since around June 29. At least one article (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 (vsnet-campaign 286, 347). The long outburst has finally faded around July 16 (<15.0) (vsnet-campaign-dn 30).

A bright long outburst in September - October

R. Stubbings detected the other bright outburst at 13.9mag on September 24. (vsnet-campaign 511, vsnet-campaign-dn 177). R. Stubbings reported <14.4 and <14.0 mag on October 4 and 8, respectively, which indicated the fading from this bright outburst (vsnet-campaign-dn 192).
