RX J1155.4-5641: new SU UMa star We have received a report that Berto Monard has confirmed superhumps with a period of 0.0622 d (cf. vsnet-alert 7264). The object is now established as a genuine SU UMa-type dwarf nova. Since the superhump period is relatively short in spite of the low outburst amplitude and relatively frequent outbursts, the star may be something relatively exceptional among short-period SU UMa systems. Further observations are strongly encouraged. Regards, Taichi Kato VSNET Collaboration team
