NED Abstract

Copyright by Central Bureau for Astronomical Telegrams. 2013CBET.3544A...1C Electronic Telegram No. 3544 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION Cox, L.; Newton, J.; Puckett, T.; Brimacombe, J.; Balam, D. D.; Graham, M. L.; Hsiao, E. Y. SUPERNOVA 2013cw IN NGC 6211 = PSN J16412717+5747050 L. Cox, J. Newton, and T. Puckett report the discovery of an apparent supernova (mag 16.9) on unfiltered CCD images (limiting mag 19.0) taken with a 0.40-m reflector at Portal, AZ, U.S.A., on May 29.357 UT in the course of the Puckett Observatory Supernova Search. The new object, which was confirmed on May 30.1469 at mag 16.9 on images (limiting mag 19.1) taken by Puckett with the 0.40-m reflector at Portal, is located at R.A. = 16h41m27s.17, Decl. = +57o47'05".0 (equinox 2000.0), which is 3".9 west and 3".2 north of the center of NGC 6211. A finding image is located at the following website URL: http://www.possdata.com/PSNJ16412717+5747050.jpg. The variable was designated PSN J16412717+5747050 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2013cw based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2013cw: Feb. 27, [19.1 (Puckett); May 31.417, 17.2 (J. Brimacombe, Cairns, Australia; remotely with a 51-cm telescope + luminance filter located at the New Mexico Skies observatory near Mayhill, NM, U.S.A.; position end figures 27s.20, 04".9; image posted at URL http://www.flickr.com/photos/43846774@N02/8935489382/). D. D. Balam, Dominion Astrophysical Observatory, National Research Council of Canada; M. L. Graham, Las Cumbres Observatory Global Telescope; and E. Y. Hsiao, Las Campanas Observatory, report that a spectrogram (range 369-700 nm, resolution 0.3 nm) of PSN J16412717+5747050 = 2013cw, obtained on June 3.34 UT with the 1.82-m Plaskett Telescope of the National Research Council of Canada, shows it to be a type-Ia supernova near maximum light. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (Blondin and Tonry 2007, Ap.J. 666, 1024) indicates that 2013cw is most similar to the type-Ia supernova 2003du at 6 days pre-maximum. After removal of the host-galaxy recession velocity of 5273 km/s (Wegner et al. 2003, A.J. 126, 2268-2280), the absorption minimum of the Si II 635.5-nm line is found to be blueshifted by about 12200 km/s.
