Ulisse Munari, Istituto Nazionale di Astrofisica, Padova Astronomical Observatory, obtained an under-exposed spectrum (peak S/N = 28; range 330-740 nm; dispersion 0.23 nm/pixel) of PSN J10435372+1140177 in a very short break (5 min) in the thick cloud cover over Asiago Observatory on Mar. 17.77 UT with the 1.22-m reflector (+ Boller & Chivens spectrograph). The spectrum tracing corresponds to a very blue (hot) continuum, essentially featureless, with no absorption bands and no detectable emission lines, resembling a black-body energy distribution, similar to what is seen in a cataclysmic variable close to maximum brightness. Munari adds that Antonio Vagnozzi and Flavio Castellani (ANS Collaboration) measured magnitudes B = 13.71 and V = 13.81 on Mar. 17.94, and B = 13.58 and V = 13.63 on Mar. 18.85.
