T. Kryachko, S. Korotkiy and B.Satovskiy (Astrotel obs., KSU) report the discovery of an apparent supernova (mag approximately 18.4) on five unfiltered images with an exposure of 300 sec. (lim mag 21.0) obtained on feb. 13.76 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. = 08h58m155s.88 +/- 0".1, Decl. = +23d03'42".4 +/- 0".1 (equinox 2000.0), which is about 3,2" west and 1,3" north of the center of SDSS J085856.01+230341.0 galaxy (R.A. = 08h58m56.01s, Decl = +23d03'41".1). Nothing is visible at this position on the Palomar Sky Survey (POSS-II red) obtained 1993-03-22 (via the Digitized Sky Survey; limiting mag 21.0) and on SDSS image. In MPChecker no asteroids.

this object has been imaged at Mandi Observatory with the 0.45m f:4.5 telescope+CCD. I can confirm the PSN on 4 coadded 120s unfiltered frames, at position RA=08 58 55.91, Dec=+23 03 42, mag=18.5mV (limiting mag=19.8mV). On the POSS-Red plate, (limiting mag = 21.5)at the same position, a 19.5m anonymous galaxy is visible. Paolo Corelli-Pagnacco-Italy
