Electronic Telegram No. 3949 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION CBAT Director: Daniel W. E.

Hayakawa, W. Zheng, and A. V. Filippenko, University of California at Berkeley, report the LOSS discovery of an apparent supernova in UGC 12182 on unfiltered KAIT images: SN 2014 UT R.A. (2000.0) Decl. Mag. Offset 2014ck June 29.47 22 45 38.88 +73 09 42.7 16.4 4".3 E, 0".5 S A finding chart was posted by the discoverers at the following website URL: http://astro.berkeley.edu/~zwk/findingchart/PSN_J22453888+73094273.jpg. SN 2006fp also appeared in UGC 12182 (cf. IAUC 8750, CBET 625). The variable was designated PSN J22453888+7309427 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2014ck based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2014ck: June 24.5 UT, 17.0 (KAIT; marginal detection; approximate R-band magnitude); 28.47, 16.4 (KAIT); 30.833, 16.1 (G. Masi; remotely using a 36-cm Schimdt-Cassegrain reflector at Ceccano, Italy; position end figures 38s.72, 43".2); July 1.381, 17.3 (J. Brimacombe, Cairns, Australia; remotely using a 51-cm RCOS telescope + STXL-6303 camera at the New Mexico Skies observatory near Mayhill, NM, U.S.A.; position end figures 38s.76, 43".4; image posted at URL https://www.flickr.com/photos/43846774@N02/14369054400/); 1.907, 16.1 (N. James, Chelmsford, Essex, England; Celestron 11 telescope + ST9XE camera; magnitude specified as R-band; position end figures 38s.75, 43".2; image accessible via website URL http://tinyurl.com/nuxw6rk). W. Zheng, I. Shivvers, K. I. Clubb, and A. V. Filippenko, University of California, Berkeley; and R. J. Foley, University of Illinois, report that inspection of a CCD spectrogram (range 350-1000 nm), obtained on June 30.455 UT with the Shane 3-m reflector (+ Kast spectrograph) at Lick Observatory, shows that PSN J22453888+7309427 = SN 2014ck is a peculiar type-Ia supernova. Cross-correlation with a library of supernova spectra using the "SuperNova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) indicates a similarity with the peculiar type-Ia supernovae 2005hk and 2002cx about a week before maximum light. The spectrum shows a blue continuum with relatively weak and narrow Si II 635.5-nm absorption, but the Fe III lines at 430 and 500 nm are clearly present, suggesting that the object might be a member of the type-Iax class of supernovae (Foley et al. 2013, Ap.J. 767, 57). L. Tomasella, P. Ochner, S. Benetti, A. Pastorello, E. Cappellaro, L. Tartaglia, N. Elias-Rosa, and M. Turatto, Osservatorio Astronomico di Padova, INAF, report that an optical spectrogram (range 340-820 nm; resolution 1.3 nm) of PSN J22453888+7309427 = SN 2014ck, obtained on July 3.98 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC) under the Asiago Transient Classification Program (Tomasella et al. 2014, as posted at http://arxiv.org/abs/1403.7233) shows that this is a 2002cx-like type-Ia peculiar supernova resembling SN 2008ha (Valenti et al. 2009, Nature 459, 674) and SN 2010ae (Strinztinger et al. 2014, A.Ap. 561, 146) around maximum light, after adopting for the host galaxy (UGC 12182) a recessional velocity of 1490 km/s (Falco et al. 2000, The Updated Zwicky Catalogue). The Asiago classification spectrum is posted at website URL http://sngroup.oapd.inaf.it. Classification was made via GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383) and SNID (Blondin and Tonry 2007, Ap.J. 666, 1024).
