NED Abstract

Copyright by Central Bureau for Astronomical Telegrams. 2010CBET.2514A...1P Supernova 2010ja in NGC 2513 Electronic Telegram No. 2514 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION Pignata, G.; Cifuentes, M.; Maza, J.; Hamuy, M.; Antezana, R.; Gonzalez, L.; Cartier, R.; Forster, F.; Gonzalez, P.; Conuel, B.; Folatelli, G.; Reichart, D.; Ivarsen, K.; Haislip, J.; Crain, A.; Foster, D.; Nysewander, M.; Lacluyze, A.; Morrell, N. Abstract. SUPERNOVA 2010ja IN NGC 2513 G. Pignata, and M. Cifuentes, Universidad Andres Bello; J. Maza, M. Hamuy, R. Antezana, L. Gonzalez, R. Cartier, and F. Forster, Universidad de Chile; P. Gonzalez, Pontificia Universidad Catolica de Chile; B. Conuel, Wesleyan University; G. Folatelli, Institute for the Physics and Mathematics of the Universe (IPMU), University of Tokyo; and D. Reichart, K. Ivarsen, J. Haislip, A. Crain, D. Foster, M. Nysewander, and A. LaCluyze, University of North Carolina at Chapel Hill, on behalf of the CHASE project, report the discovery of an apparent supernova (mag approximately 17.9) on an unfiltered image taken on Oct. 15.35 UT with the 0.41-m 'PROMPT 1' telescope located at Cerro Tololo. The new object is located at R.A. = 8h02m28s.39 +/- 0".2, Decl. = +9o23'40".9 +/- 0".2 (equinox 2000.0), which is about 55" east and 68" south of the center of the galaxy NGC 2513; nothing is visible at this position on stacked archival images taken between Jan. 8.13 and Mar. 19.04 (limiting mag 19.5), but 2010ja is visible at mag approximately 18.0 on images taken on Oct. 16.34 and 17.33. N. Morrell, Las Campanas Observatory; and G. Folatelli, IPMU, University of Tokyo, reports on spectroscopic observations (range 330-950 nm) of 2010ja, obtained on Oct. 22.4 UT with the Boller and Chivens spectrograph attached to the 2.5-m du Pont telescope at Las Campanas Observatory. The low-signal-noise spectrum of 2010ja is that of an evolved type-Ia supernova; cross-correlation with a library of supernova using SNID (Blondin and Tonry 2007, Ap.J. 666, 1024) shows 2010? to be most similar to SN 1991bg at about three months after maximum light.
