Comparison of a spectrum of LRN NGC 4490−2009OT1 taken on 2011 December 21 (hence around red light curve peak) with classification spectrum of SN 2011ht obtained on 2011 September 30 (Pastorello et al. 2011). The SN 2011ht spectrum was taken at the early SN luminosity rise (∼−54 d from the V-band maximum), and before it showed the classical Type IIn spectral features.
