A spectrum, obtained on Jan. 4.32 with the 9.2-m Hobby-Eberly Telescope (+ Marcario Low-Resolution Spectrograph) by S. C. Odewahn, shows 2009nq to be a type-Ia supernova around maximum. According to SNID (Blondin and Tonry 2007, Ap.J. 666, 1024), the spectrum best resembles those of SN 2002er (at 2.5 days before maximum) and SN 1994S (at 1.4 days after maximum) at redshift z = 0.018, consistent with the redshift of NGC 7549 (z = 0.0157). The photospheric velocity, estimated from the minimum of the Si II 635.5-nm feature, and corrected for the host-galaxy redshift, is about 10200 km/s.
