2005IAUC.8487....4T

S. Taubenberger, Max-Planck-Institut fuer Astrophysik, Garching; F. Patat, European Southern Observatory; and S. Benetti, Istituto Nazionale di Astrofisica, Padua, on behalf of the ERTN (cf. IAUC 7987), report that a fully reduced spectrum (range 360- 880 nm; resolution 1.3 nm) of SN 2005ai (cf. IAUC 8486), obtained on Feb. 14.83 UT by M. Alises at the Calar Alto Observatory 2.2-m telescope (+ CAFOS), shows it to be a type-Ia supernova. The spectrum is very similar to that of SN 1994D (Patat et al. 1996, MNRAS 278, 111) at about 1 month past maximum light.
