[vsnet-alert 26393] Re: TCP J07363658+4151215: most likely helium WZ Sge-type dwarf nova

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.

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.
