> Observations on Jan 20 showed a transition to the early modulation with > 'growing' superhumps of still small amplitude and a hint of a 0.0095d alt. > 0.019d period around a mean magnitude of 12.49CR. Ordinary superhumps, yes. The amplitudes were too small to be directly visible in Hambsch's data.

[vsnet-campaign-dn 16208] TCP J07094936+1412280: appearance of ordinary superhumps

TCP J07094936+1412280: appearance of ordinary superhumps Kiyota-san, Itoh-san, Tonny Vanmunster, Stephen M. Brincat, Sano-san, Tamás Tordai, and Kyoto Univ. Obs. have reported further observations of TCP J07094936+1412280. The data on 15th Jan at Kyoto Univ. Obs. showed clear ordinary superhumps with an amplitude of ~0.15 mag. The baseline was still too short to determine its period. Continuous observations are encouraged. Best, Yusuke
