Possible superoutburst of BF Ara The suspected SU UMa-type dwarf nova BF Ara is undergoing a long outburst. The previous long outburst occurred in late March, making the interval between them around 90 d (one of the shortest, if proven to be a genuine SU UMa star). Time-resolved photometry is encouraged.
