L. Tomasella, S. Valenti, S. Benetti, F. Bufano, M. Fiaschi, A. Pastorello, and P. Ochner, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica, on behalf of a larger collaboration, report that a spectrogram of 2011ji, obtained on Dec. 24.02 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC; range 350-820 nm; resolution 2.4 nm), suggests that 2011ji is a type-Ia supernova around one month after maximum. Using GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383; available at website URL https://gelato.tng.iac.es/login.cgi), the spectrum is found to be similar to that of SN 1999gp at 34 days past maximum. A narrow H_alpha feature is visible in the spectrum, fixing the redshift at z = 0.089. However, because of the poor resolution of the spectrum, it cannot be verified if H_alpha is circumstellar or due to a contaminating H II region.
