T. Boles, Coddenham, England, reports the discovery of an apparent supernova (mag 18.3) on unfiltered CCD images taken on Feb. 11.868 and 13.066 UT with a 0.35-m reflector. The new object is located at R.A. = 9:35:56.03, Decl. = +74:00:00.6 (equinox 2000.0; average from fifteen images), which is approximately 6".9 east and 3".3 north of the center of PGC 27294 (= MCG +12-9-56). Nothing is present at this position on Boles' images from 2006 Mar. 5 and 2006 Jan. 20 (limiting mag 19.5) or on Digitized Sky Survey plates from 1991 Dec. 6 (limiting red mag 20.5) and 1952 Aug. 22 (limiting blue mag 21.0). Following posting on the Central Bureau's unconfirmed-objects webpage, P. Corelli, Pagnacco, Italy, reports magnitude 18.3 and position end figures 55s.89, 00".3 for 2010ab from a eight 90-s co-added unfiltered CCD frames taken on Feb. 13.92 with a 45-cm f/4.4 reflector. G. Cortini and S. Antonellini, Predappio, Italy, report that 2010ab was at magnitude near 17.8 on Feb. 14.02 (100-s exposure with a Celestron 14 telescope and a Starlight X-press MX 916 camera). J. Brimacombe, Cairns, Australia, using a remotely operated 50-cm reflector (+ STL6K camera) at New Mexico Skies, Mayhill, NM, U.S.A., measured mag 18.9 (and offset 7" east and 3" north of the host-galaxy core) for 2010ab from five 600-s co-added images (limiting magnitude 20) on Feb. 14.08, adding that nothing is visible at this position on Digitized Sky Survey images (limiting mag 20.5); he has posted his image at the following website URL: http://www.flickr.com/photos/43846774@N02/4356068574/
