TCP J09370380+1657350: superhump period

   Thanks to the efforts by Itoh-san, Kyoto U. team,
Josch Hambsch and Tamas Tordai, the period of
ordinary superhumps has been determined.
The mean period since Jan. 21 has been 0.0624(1) d,
only 0.8% longer than the orbital period.
The mean amplitude of superhumps is also low
(0.05 mag).  These values suggest a small mass ratio.
