T. Kryachko, S. Korotkiy, and B. Satovskiy report the discovery of an apparent supernova (mag approximately 18.3) on five unfiltered CCD images (limiting mag 21.0) obtained on Nov. 1.83 UT with a 30-cm Takahashi FRC-300 telescope (+ CCD Apogee Alta U9000 camera) at Kazan State University's Astrotel Observatory near Karachay-Cherkessia, Russia. The new object is located at R.A. = 2:32:07.96 ± 0".1, Decl. = +41:05:00.5 ± 0".1 (equinox 2000.0), which is about 6".9 east and 1".5 south of the center of the apparent host galaxy (which they name as PGC 2802359). The discovery image is posted at URL http://www.astroalert.su/files/pgc2802359_psn.png. The variable was designated PSN J02320796+4105005 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011hx based on the spectroscopic confirmation reported below. Additional magnitudes for 2011hx (obtained via unfiltered CCD unless noted otherwise): 1989 Sept. 3, [21.0 (Palomar Sky Survey red plate, via the Digitized Sky Survey; via Kryachko et al.); 2011 Nov. 14.783, 16.2 (V.
