Pavel Balanutsa and Vladimir Lipunov report that the MASTER-Net auto- detection system at Tunka (http://observ.pereplet.ru) detected an apparent supernova (mag 17.1) on a 180-s unfiltered CCD exposure (limiting mag 19.4) taken on Aug. 30.70 UT. The new object is located at R.A. = 17:52:42.98, Decl. = +29:04:10.6, (equinox 2000.0; uncertainty 0".2), which is 46" east and 38" north of the galaxy UGC 11021. Nothing is visible at this position on a MASTER/Tunka reference image from June 22.75 (limiting mag 19.0). The variable was designated PSN J17524298+2904106 when posted at the Central Bureau's TOCP webpage and is here designated SN 2011ft based on the spectroscopic report below.
