TCP J17242302+3258109: Possible appearance of ordinary superhumps Kiyota-san and Kyoto Univ. Obs. have reported the observation of TCP J17242302+3258109. Time-resolved observation on 19th Nov. at Kyoto Univ. Obs. showed a large amplitude (~0.2 mags) variation, which can be ordinary superhumps. Due to the limited visibility, the baseline was not enough to determine its variation period. Best, Yusuke
