RZ Sge: possible outburst According to AAVSO New Flash No. 370, the SU UMa-type dwarf nova RZ Sge may be in outburst. G. Chaple Jr. (USA) reported the object at mag 12.8 on Dec. 1.953 UT. The latest superoutburst of RZ Sge was observed in 1997 August - September; there is a good chance the present outburst (if confirmed) may evolve into a superoutburst. Regards, Taichi Kato
