S. Nakano, Sumoto, Japan, reports the discovery of an apparent supernova (mag 14.9) by K. Itagaki (Teppo-cho, Yamagata, Japan) on unfiltered CCD frames taken around Nov. 24.86 UT with a 0.60-m f/5.7 reflector; confirming images from Nov. 25.764 show 2006ov at mag 14.8. The new object is located at R.A. = 12h21m55s.30, Decl. = +4o29'16".7 (equinox 2000.0), which is 5".5 north and 51" north of the center of M61 (NGC 4303). Nothing was visible at this location on Itagaki's exposures from 2006 May 4 and earlier (limiting mag 19.5) or on the Digital Sky Survey. Nakano also forwards the following position end figures from an unfiltered CCD exposure by K. Kadota (Ageo, Saitama-ken, Japan, 0.25-m reflector) on Nov. 25.770, with 2006ov measured at mag 15.0: 55s.30, 16".6.
