Green; Hoffman Lab 209; Harvard University; 20 Oxford St.; Cambridge, MA 02138; U.S.A. e-mail: cbatiau@eps.harvard.edu (alternate cbat@iau.org) URL http://www.cbat.eps.harvard.edu/index.html Prepared using the Tamkin Foundation Computer Network SUPERNOVA 2011iq Vladimir Lipunov reports the discovery of an optical transient (mag 18.3) on unfiltered CCD images (limiting mag 20.3) taken by the MASTER-net auto- detection system (see website URL (http://observ.pereplet.ru) at Kislovodsk, Russia, on Oct. 29.36 UT using two 40-cm telescope tubes (+ Apogee CCD Alta U16m camera; field-of-view 2 deg x 4 deg). The new object is located at R.A. = 2h48m49s.60, Decl. = -8d04'30".0 (equinox 2000.0, presumed). A galaxy of magnitude g = 21.3 in the Sloan Digital Sky Survey is very close to this position. L. Tomasella, A. Pastorello, S. Valenti, and S. Benetti, Istituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova, on behalf of a larger collaboration, report that a spectrogram of 2011iq, obtained on Nov. 28.01 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC; range 350-820 nm; resolution 2.4 nm), shows it to be a type-Ia supernova. Cross-correlation with a library of supernova spectra via the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) indicates that 2011iq is a type-Ia supernova about 20 days after maximum light at a redshift of about 0.015.
