S. Nakano, Sumoto, Japan, reports the discovery by Masaki Tsuboi (Kuchita-minami, Asakita-ku, Hiroshima, Japan) of an apparent supernova (mag 16.2) on a 30-s unfiltered CCD frame taken on July 20.48 UT using a 0.30-m f/5.3 reflector (+ ST-2000XM camera); Tsuboi confirmed the object on two frames taken two hours later using the same instrument (limiting magnitude 17.5). The new object was measured by Tsuboi to be located at R.A. = 11:18:31.7, Decl. = +57:58:37.2 (equinox 2000.0), or 35".5 west and 83".0 south of the center of NGC 3613. The variable was designated as PSN J11183170+5758372 when posted at the Central Bureau's TOCP webpage and is here designated SN 2011eh based on the spectroscopic report below. Tsuboi adds that nothing is visible at the position of 2011eh on two frames taken on 2011 May 19.599 and June 3.577 using the same instrument, and that nothing is visible to limiting red mag 19 or fainter on Digitized Sky Survey images.
