B. Dintinjana and H. Mikuz, Crni Vrh Observatory, report the discovery of an apparent supernova (mag 15.7) by H. Mikuz on four unfiltered CCD images (bandpass roughly equivalent to the R band) taken on Nov. 18.720-18.751 UT with the 60-cm f/3.3 Cichocki reflector in the course of the Comet and Asteroid Search Program (PIKA) at Crni Vrh Observatory. The new object is located at R.A. = 22:26:14.54, Decl. = +34:12:59.1 (equinox 2000.0; uncertainty about 0".2), which is approximately 8" east and 1" north of the center of a nearby galaxy. They add that nothing is visible at this position on several Digitized Sky Survey red and blue images from the Palomar Sky Survey. The discovery image is at URL http://www.observatorij.org/vstars/PSN20111118/PSN20111118.jpg. The variable was designated PSN J22261454+3412591 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011hw based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2011hw (unfiltered unless noted otherwise): 2008 Dec. 7, [19.0 (PIKA; R-band); 2010 Dec. 12, [19.5 (PIKA); 2011 Nov. 19.848, R = 15.84 ± 0.03 (B. Dintinjana and J. Skvarc, Crni Vrh; comparison stars from the USNO-B1 catalogue); 20.15, 16.8 (R. A. Koff, Bennett, CO, USA; Meade 0.25-m f/10 reflector + Apogee AP-47p camera; limiting magnitude 19.3; position end figures 14s.57, 58".1; UCAC3 reference stars).
