KM Lac photometry From observations on Nov. 20, 21, 22, the slow undulations (cf. vsnet-alert 3729) seem to persist both in combined light with the nearby star and PSF photometry (barely resolved). Period analysis suggests candidate periodicities longer than 0.1 d. Long runs and/or multi-longitude coverage are needed to clarify the nature of the object. Regards, Taichi Kato
