NED Abstract

Copyright by Central Bureau for Astronomical Telegrams. 2009CBET.1665A...1S Supernovae 2009I, 2009J, and 2009K Electronic Telegram No. 1665 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION Stritzinger, M. Abstract. SUPERNOVAE 2009I, 2009J, AND 2009K M. Stritzinger, Las Campanas Observatory (LCO), on behalf of the Carnegie Supernova Project, reports that he obtained spectra (range 380-940 nm) of 2009I (cf. CBET 1660), 2009J (cf. CBET 1661), and 2009K (cf. 1663) on Jan. 17.1 UT with the 6.5-m Magellan II (Clay) telecope (+ LDSS3). The spectrum of 2009I reveals it to be a young type-Ia supernova. Comparison with a library of spectra via the "Supernova Identification"code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) suggests that 2009I is very similar to SN 2003du at 7-10 days before maximum; adopting a host-galaxy recession velocity of 7845 km/s (Catinella et al. 2005, A.J. 130, 1037) for the host galaxy (NGC 1080), Si II is measured to be blue-shifted by roughly 11000 km/s. Supernova 2009J appears to be a peculiar type-Ia supernova; with the aid of SNID, he finds this event to be most similar to SN 2005hk a few days past maximum. Supernova 2009K is a young type-II event soon after explosion; its spectrum exhibits shallow P-Cyg profiles of the Balmer series and He I (587.6 nm). E. Prosperi, Castelmartini, Italy, reports the following unfiltered CCD magnitudes obtained with a 0.35-m f/10 Schmidt-Cassegrain reflector: SN 2009I, Jan. 16.845 UT, 16.6; SN 2009K, Jan. 16.872, 16.1. Peter Marples, Loganholme, Queensland, Australia, reports his independent discovery of SN 2009J on a CCD image takenon Jan. 14.456 UT with a 30-cm reflector (+ Starlight Xpress camera). C. Drescher (Brisbane) measured red mag 17.5 and the following position for 2009J, apparently from Marples' discovery frame: R.A. = 5h55m21s.09, Decl. = -76o55'20".7 (equinox 2000.0).
