L. Tomasella, S. Valenti, S. Benetti, and P. Ochner, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica; and A. Pastorello, Dipartimento di Astronomia, Universita di Padova, report that a spectrogram of TCP J04283707+3157578 (range 360-810 nm; resolution 2.2 nm) was obtained on Sept. 26.10 UT with the Ekar-Copernico 1.82-m telescope (+ AFOSC). The spectrum shows a strong H_alpha emission. Compared to H_alpha, H_beta is weak but also perceptible: the possible absorption dips surrounding H_beta could be the residual effect of the accretion disk following outburst, as is typically evident in dwarf novae (Szkody et al. 1990, Ap.J. Suppl. 73, 441). There is a trace of He I emission at 587.6 nm, while all other expected lines seems to have drowned in the noise. So the classification of this object as a cataclysmic variable is plausible.
