dc.description.abstract | Report the discovery of an apparent supernova in public images from the Catalina Sky Survey (CSS). SN 2012 UT R.A. (2000.0) Decl. Mag. Offset 2012cr May 25.15 12 42 24.45 - 7 02 57.6 18.3 12".7 W, 18".2 S The variable was designated PSN J12422445-0702576 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012cr based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2012cr: Mar. 30.33 UT, [19.5 (CSS); May 25.920, 17.5 (Giancarlo Cortini, Predappio, Italy; Celestron C14 reflector + SXVR-H9 camera); 27.258, 17.5 (Joseph Brimacombe, Cairns, Australia; luminance filter; position end figures 24s.52, 57".6). Brimacombe's image is posted at the following website URL: http://www.flickr.com/photos/43846774@N02/7290971272/. Y. Cao, California Institute of Technology; M. M. Kasliwal, Carnegie Institute for Science and Princeton University; and C. J. White, Princeton University, report spectroscopic follow-up of PSN J12422445-0702576 = 2012cr on May 30.14 UT with the Dual Imaging Spectrograph mounted on the ARC 3.5-m telescope at the Apache Point Observatory. Broad H_alpha emission resembles that seen in normal type-II supernovae at about several days after maximum brightness. The H_alpha has a FWHM of about 18000 km/s. Narrow H_alpha, nitrogen, and sulfur lines suggest a redshift of about 0.009, consistent with the redshift of its host galaxy, NGC 4626. | |
