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.
