H. Yamaoka, Kyushu University, reports the discovery by Koichi Itagaki (Yamagata, Japan) of a possible supernova (mag 15.8) on an unfiltered CCD image taken on Jan. 7.431 UT with a 0.30-m reflector at Takanezawa, Tochigi. The new object was not detected on Itagaki's image taken on Jan. 2.447 (limiting mag 18.5), but it does appear at mag 17.5 on his image taken on Jan. 5.570. The variable is located at R.A. = 8:55:48.50, Decl. = +78:13:02.7 (equinox 2000.0), which is 31".7 east and 21".4 south of the nucleus of NGC 2655. Itagaki's discovery image can be seen at the following website URL: http://www.k-itagaki.jp/images/psn2655.jpg. Yamaoka adds that Ken-ichi Kadota (Ageo, Saitama, Japan) confirmed 2011B at mag 15.9 on co-added images taken on Jan. 7.724 with a 0.25-m reflector, from which he measured position end figures 48s.03, 01".5. Yamaoka also forwards a report from M. Koishikawa, Sendai Astronomical Observatory (SAO), who notes that 2011B is not visible detected on a CCD image (limiting mag about 19.0) taken on Jan. 3.735 UT with the SAO 1.3-m reflector.
