2009CBET.1955....2S

D. K. Sahu, G. C. Anupama, and U. K. Gurugubelli, Indian Institute of Astrophysics, Bangalore, report that a low-resolution spectrogram (range 350-920 nm) of 2009jf, obtained on Sept 29.6 UT with the Indian Astronomical Observatory's 2-m Himalayan Chandra Telescope (+ HFOSC), shows it to be a type-Ib supernova. Using the SNID code (Blondin and Tonry 2007, Ap.J. 666, 1024), the spectrum of 2009jf is found to be similar to that of SN 1999ex close to maximum light. Adopting a recession velocity of 2381 km/s for the host galaxy (Haynes et al. 1998, A.J. 115, 62), the velocity corresponding to the He I 587.6 line is 16900 km/s.
