TCP J07363658+4151215: most likely helium WZ Sge-type dwarf nova
Kyoto U. team has reported observations. The data show early superhumps with an amplitudes of 0.05 mag. The period is 0.0280(2) d. This object is most likely a helium WZ Sge star. The SDSS color (very blue u-g=+0.27) is consistent.
Kyoto U. team spectroscopically observed this object by the 3.8m-telescope Seimei. The object shows Hbeta and gamma absorption lines, so the object is not helium-rich. However, this object will be a WZ Sge star, and hence it is worth observing. Continuous photometry is encouraged.
