2011CBET.2965....3M

N. Morrell, Las Campanas Observatory, reports on an optical spectrogram (range 363-920 nm) of PSN J02580760-1021541 = SN 2011jp obtained on Dec. 29.23 UT by Povilas Palunas with the 2.5-m Las Campanas du Pont telescope (+ WFCCD), which shows that 2011jp is a type-II supernova. Cross-correlation with a library of supernova spectra by means of the Supernova Identification tool (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) gives good matches with a number of type-II-P supernovae between 10 and 20 days after maximum light. From the minimum of the H_beta absorption, an expansion velocity of roughly 6000 km/s is derived, if the NED recession velocity of 4653 km/s (Huchra et al. 1993, A.J. 105, 1637) is assumed for NGC 1154.
