We report that an optical spectrogram (range 340-820 nm; resolution 1.3 nm) of
PSN J08510815+7150339, obtained on Jan. 25.76 UT with the Asiago
1.82-m Copernico Telescope (+ AFOSC), shows it to be a normal type-Ia supernova.
Adopting for the host galaxy (PGC 24869) a recessional velocity of 3485 km/s
(Strauss et al. 1992, ApJS 83, 29; via NED), a good match is found with type-Ia
supernova 1994D about 20 days after B-band maximum light (Patat et al. 1996, MNRAS 278, 111).
An expansion velocity of
about 10000 km/s is derived from the minimum of the Si II 635-nm line.

et al. 2008, A.Ap. 488, 383) and SNID (Blondin and Tonry 2007, Ap.J. 666, 1024).
