T. Kryachko, A. Samohvalov, S. Korotkiy and B.Satovskiy (Astrotel obs., KSU) report the discovery of an apparent supernova (mag approximately 19.5) on five unfiltered images with an exposure of 300 sec. (lim mag 21.5) obtained on oct. 27.75 UT with the Takahashi FRC-300 (D=300mm, F=2330mm) + CCD Apogee Alta U9000 at Kazan State University Astrotel observatory (Karachay-Cherkessia, Russia, MPCCOD: 114). The new object is located at R.A. = 02h48m28s.95 +/- 0".1, Decl. = +31d19'33".5 +/- 0".1 (equinox 2000.0), which is about 5,7" west and 1,2" north of the center of anonymous galaxy (R.A. = 02h48m29.33s, Decl = +31d19'32".3). Nothing is visible at this position on the Palomar Sky Survey (POSS-II red) obtained 1991-10-05 (via the Digitized Sky Survey; limiting mag 21.0) and on SDSS image. In MPChecker no asteroids.
