KM Lac variability From the 5.7-hour run of KM Lac on Nov. 26 (Makoto Uemura and Taichi Kato), both combined magnitudes and PSF photometry seem to indicate the presence of a shallow fading centered around 26.51 UT. The profile resembles that of a short eclipse in CVs. The object being reported still bright, observers are strongly encouraged to monitor the object as long as possible to determine the possible periodicity. Regards, Taichi Kato and Makoto Uemura
