[dwarf nova] Otpical transient in Psc = OT J230425.8+062546 : a spectrum

We obtained an optical spectrum of a new transient in Psc (= OT J230425.8+062546) using 1.3m Araki telescope with LOSA/F2(R~550) on Jan.03. The object was discovered by H. Nishiura on 2010 Dec. 29(c.f. CBET 2616). The figure shows our preliminary results of a spectrum of the object. The spectra shows absorptions of H-beta, H-gamma and a emission of H-alpha on a blue continuum.   These results suggest that the object would be a dwarf nova as reported by the other observers (c.f. CBET 2617).
