Abstract (from CDS):

L. Magill, Queen's University, Belfast, and Isaac Newton Group; R. Kotak and S. Smartt, Queen's University, Belfast; and A. Pastorello, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica, report that an optical spectrogram (range 330-900 nm) of PSN J00415140+3259234 = SN 2011fq was obtained at the William Herschel Telescope (+ ISIS spectrograph) by K. Maguire on Sept. 3.08 UT. The spectrum displays a prominent H_alpha component, with a distinct P-Cyg profile. The expansion velocity of H_alpha, as estimated from the blue edge of the absorption trough of this line, is about 9000 km/s, after correcting for the recession velocity of UGC 442 (4430 km/s, from Falco et al. 1998, The Updated Zwicky Catalogue; via the NED website). The Ca II near-infrared triplet is also present with a P-Cyg profile, as well as Na I D and Fe II lines. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) suggests a normal type-II-plateau supernova, similar to SN 2004et at an epoch of about 35 days post-maximum (Sahu et al. 2006, MNRAS 372, 1315).
