NED Abstract

Copyright by Central Bureau for Astronomical Telegrams. 2013CBET.3768A...1N Electronic Telegram No. 3768 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION CBAT Director: Daniel W. E. Green; Hoffman Lab 209; Harvard University; SUPERNOVA 2013hq IN NGC 7276 = PSN J22241321+3605008 S. Nakano, Sumoto, Japan, reports the discovery by Koichi Itagaki (Teppo-cho, Yamagata) of an apparent supernova (mag 17.1) on an unfiltered CCD frame (limiting magnitude 18.5) taken on Dec. 13.384 UT using a 0.50-m f/6.8 reflector at the Takanezawa station, Tochigi-ken. The new object is located at R.A. = 22h24m13s.21, Decl. = +36d05'00".8 (equinox 2000.0), which is 14" west and 14" south of the center of NGC 7276. The discovery image was posted at website URL http://www.k-itagaki.jp/images/7276.jpg. The variable was designated PSN J22241321+3605008 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2013hq based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2013hq: Nov. 28.480, [18.0 (Itagaki); Dec. 13.484, 17.2 (T. Noguchi, Katori, Chiba-ken, Japan; 0.23-m f/6.3 Schmidt-Cassegrain reflector + BITRAN BT-11E camera; limiting magnitude 18.5; position end figures 13s.18, 00".8; image posted at website URL http://park8.wakwak.com/~ngc/images/PSNinNGC7276.jpg; communicated by Nakano); 13.773, 16.3 (Gianluca Masi, Francesca Nocentini, and Patrick Schmeer; remotely using a 43-cm telescope near Ceccano, Italy; position end figures 13s.16, 00".8); 13.843, 16.6 (Massimiliano Martignoni, Magnago, Italy; 0.25-m f/10 Schmidt-Cassegrain reflector; position end figures 13s.15, 00".7; PPMXL reference stars); 14.148, 16.4 (T. Yusa, Osaki, Japan; 0.25-m f/3.4 hyperbolic astrograph + SBIG ST-10XME camera at the RAS Observatory near Mayhill, NM, U.S.A.; limiting mag 18.0; six stacked 120-s exposures; position end figures 13s.21, 00".7; UCAC4 reference stars; image posted at website URL http://space.geocities.jp/yusastar77/supernova/PSNinN7276_131214.htm); 15.824, 16.6 (Federica Luppi and Luca Buzzi, Varese, Italy; 0.60-m f/4.6 reflector; position end figures 13s.19, 00".7; reference stars from CMC-14 catalogue; image posted at URL http://www.astrogeo.va.it/pub/TOCP/PSN_N7276.jpg); 16.081, 16.9 (Joseph Brimacombe, Cairns, Australia; remotely using a 51-cm RCOS telescope + STXL-6303 camera at the New Mexico Skies observatory near Mayhill; position end figures 13s.21, 00".7); 17.060, 16.8 (Brimacombe; image posted at website URL http://www.flickr.com/photos/43846774@N02/11532899014/; position end figures 13s.21, 00".6). K. Ayani, Bisei Astronomical Observatory (BAO), Ibara, Okayama, Japan, obtained a low-resolution spectrogram (range 400-800 nm; resolution 0.6 nm at H-alpha) of PSN J22241321+3605008 = SN 2013hq with the BAO 1.01-m telescope on Dec. 24.45 UT. The spectrum is that of a type-Ia supernova several days after maximum. Cross-correlation with a library of supernova spectra using the "SuperNova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows that 2013hq matches with SN 1992A at seven days after maximum. Assuming that the heliocentric velocity of NGC 7276 of 5980 km/s (Huchra et al. 1999, Ap.J. Suppl. 121, 287), the blueshift of the Si II 635.5-nm absorption is about 10000 km/s.
