Di Mille et. al., University of Padova and others report on CBET 1284 that a spectrogram of this possible nova was obtained at Asiago Observatory (Istituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova) on Mar. 2.80 UT with the 1.82-m telescope (+ AFOSC). The spectrum shows bright Balmer emission lines with FWHM of about 1700 km/s. Fe II multiplets (42, 49, 74), Na I D, and possible O I 777.3-nm emissions are also detected, confirming that this object is a nova in the early decline phase and belongs to the "Fe II" class of the Tololo classification scheme.

Blondin, Harvard-Smithsonian Center for Astrophysics (CfA), report that a spectrum obtained on Mar. 4.37 UT shows it to be a young, reddened, peculiar, type-II supernova. The spectrum is similar to an early spectrum of the peculiar type-II supernova 1987A taken on 1987 Feb. 25 UT (i.e., roughly two days past the neutrino outburst and 82 days before V-band maximum light.
