J.-J. Zhang, Yunnan Astronimical Observatory (YNAO); X.-F. Wang, Tsinghua University, report on an optical spectrogram (range 350-890 nm) of PSN J14005449+4058596 that was obtained on 2014 April 19.73 UT with the 2.4-m telescope (+YFOSC) at LiJiang Gaomeigu Station of YNAO. The spectrum is consistent with a broad-lined type Ic supernova a few days before the maximum light. Cross-correlation with a library of supernova spectra using the GELATO (Harutyunyan et al. 2008, A.Ap., 488, 383) shows that it matches with SN 2006aj at t = - 5 days. The spectrum is superimposed by some narrow emission lines of H and O [III], likely due to the light contamination from the nearby H II region. Follow up observations of this object are highly encouraged.
