T.-M. Zhang, National Astronomical Observatories of China; J.-J. Zhang, Yunnan Astronomical Observatory of China (YNAO); and X.-F. Wang, Tsinghua Center for Astrophysics, Tsinghua University, report on an optical spectrogram (range 350-700 nm) of PSN J08544603+3932161 = SN 2011hr that was obtained on Nov. 10.9 UT with the YNAO 2.4-m telescope (+ YFOSC) at LiJiang Gaomeigu Station. The spectrum is very blue, consistent with a type-Ia supernova of the 1991T-like subclass at about one week before maximum light, with Fe lines dominating. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows that the spectrum of 2011hr matches that of SN 1997br at -7 days.
