V585 Lyr: definite superoutburst of a new short-period SU UMa star! Dear Colleagues, As earlier reported, V585 Lyr now exhibits definte superhumps! A preliminary analysis of the early data yielded a period of 0.0603(3) d. The growth time of the superhumps was determined to be about 3 d, which is compatible with the short superhump period. Upon closer examination of the initial data, there is no clear evidence of early superhumps; the low-amplitude (~0.1 mag) modulations more likely reflected slow modulations (some sort of wave in the disk?). There even seems to be some evidence of super-QPOs in the September 17 data, which are QPOs only observed during the limited stages of a superoutburst (cf. Kato et al. 1992, PASJ 44, L215; Kato 2002, PASJ 54, 87). We seem to have succeeded in covering the most interesting part of the entire outburst light curve! The object seems to bear some resemblance to SW UMa in its outburst properties and superhump profiles. Although these sets of cicumstantial evidence does not strongly support a system resembling WZ Sge-type object, the short superhump period would surely qualify the object as the most emergent and astrophysically interesting dwarf nova. Please make as long observations as possible, and report your observations to vsnet-campaign-report. Regards, Taichi Kato VSNET Collaboration team
