Supernova 2013gd in MCG -01-10-39 = Psn J03490564-0303283

Further to CBET 3678, C. Casper, K. L. Fuller, W. Zheng, W. Li, and A. V. Filippenko, University of California at Berkeley; and S. B. Cenko, Goddard Space Flight Center, report the LOSS discovery of a supernova in MCG -01-10-39 on unfiltered KAIT images: SN 2013 UT R.A. (2000.0) Decl. Mag. Offset 2013gd Nov. 9.35 3 49 05.64 - 3 03 28.3 16.9 2".5 E, 9".5 N A finding chart for the new object was posted at the following website URL: http://astro.berkeley.edu/~zwk/findingchart/PSN_J03490564-03032833.jpg. The variable was designated PSN J03490564-0303283 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2013gd based on the spectroscopic confirmation reported below. Additional approximate CCD magnitudes for 2013gd: Nov. 5.3 UT, [18.5 (KAIT); 10.075, 16.3 (Gianluca Masi, Francesca Nocentini, and Patrick Schmeer; remotely using a 43-cm robotic telescope near Ceccano, Italy; position end figures 05s.67, 28".6); 10.3, 16.8 (KAIT); 10.329, 16.8 (Joseph Brimacombe, Cairns, Australia; remotely with a 51-cm RCOS telescope, STXL-6303 camera located at the New Mexico Skies observatory near Mayhill, NM, USA; position end figures 05s.65, 28".8; image posted at website URL http://www.flickr.com/photos/43846774@N02/10789180596/). D. Milisavljevic, Harvard-Smithsonian Center for Astrophysics; and S. Gottilla, MMT Observatory, report that a low-dispersion spectrogram (range 345-855 nm), obtained on Nov. 9.5 UT with the 6.5-m MMT telescope (+ Blue Channel), shows PSN J03490564-0303283 = SN 2013gd to be a young type-II supernova. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows an excellent match with the type-IIP event 1999gi at five days before maximum light. Using a redshift of z = 0.0134 for host galaxy, MCG -01-10-39 (from Costa et al. 1998, A.J. 116, 1; via NED), they estimate the minimum of the H_alpha P-Cyg absorption to be blueshifted by approximately 12700 km/s.
