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 PSN J12471442-1003473 = SN 2011jh, obtained on Dec. 24.20 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC; range 350-820 nm; resolution 2.4 nm), suggests that 2011jh is a type-Ia supernova several days before maximum. The best fits to these spectra found by GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383; available at https://gelato.tng.iac.es/login.cgi) suggest that 2011jh is similar to SN 2002bo (Benetti et al 2004, MNRAS 348, 261) at 10 days before maximum.
