Re: [vsnet-alert 3727] KM Lac in outburst We have performed a more detailed analysis (PSF fitting at the reported KM Lac position) of the time-series data obtained on Nov. 20. The resultant light curve seesm to indicate slow, hump-like waves. The light curve can be best fitted by a potential period of 0.095 d, which may suggest the presence of superhumps. The result, however, needs independent confirmation, since KM Lac heavily blends with the nearby star on our images. Follow-up observations are strongly requested. Regards, Taichi Kato Makoto Uemura
