M. M. Kasliwal, California Institute of Technology; J. L. Howell and D. B. Fox, Pennsylvania State University; R. Quimby, California Institute of Technology; and A. Gal-Yam, Weizmann Institute, report that two 750-s exposures were obtained of 2009jf (cf. CBET 1952) on Sept. 29.119 UT with the Low Resolution Spectrograph on the Hobby Eberly Telescope, using the gr300 grating and the GG385 filter. The spectra resemble those of SN 1999ex and have prominent He I and Ca infrared in absorption. The 587.6-nm He I line is blueshifted by 14500 km/s. They conclude that 2009jf is a young type-Ib supernova.
