Re: TCP J17233734+1902555 early superhumps? After inclusion of Josch Hambsch's new data, the period of 0.05440(3) d (alias of the previous report) has become more likely. The current profile is that of early superhumps (double maxima with the brighter secondary peak).

TCP J17233734+1902555 early superhumps? Kiyota-san. Itoh-san, Tonny Vanmunster and Sano-san have reported observations. Although there were irregularities, a period of 0.06067(3) d was obtained (amplitude 0.09 mag). The profile is not inconsistent with early superhumps. Further observations will establish the nature of variations and period.
