We report that an optical spectrogram of PSN J16265528+3338244 (= MASTER OT J162655.28+333824.4, #6024), 340-820 nm; resolution 1.3 nm, obtained on March 31.98 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC), shows it to be a type-Ia supernova at redshift around 0.04. An excellent match is found with the type-Ia supernova 1994D (Patat et al. 1996, MNRAS 278, 111) few days after B-band maximum light.
An expansion velocity of about 10600 km/s is derived from the minimum of the Si II 635-nm line.
