(psn 2008 10 30.99 03 10 00.96 +19 13 23.1 17.7 U 23W 6N)


T. Kryachko (Astrotel obs., KSU) and S. Korotkiy (Ka-Dar obs., Moscow) confirmed possible supernova at coordinates: R.A.=03h 10m 00.93s +/-0.2″, DEC=+19d 13′ 23.1″ +/-0.2″ (equinox 2000.0, reduction with reference to UCAC-2) on three unfiltered images with 300 sec exposure (limiting Red-filter mag 20.0) obtained on Nov. 2.941 UT with the 80-mm ED refractor (D=80mm, F=600mm) + CCD ST-2000XM at Kazan State University Astrotel observatory (Karachay-Cherkessia, Russia). We have measured unfiltered magnitude (with R zero-point) of the supernova 16.8. Nothing is visible at this position on a Palomar Sky Survey (POSS-II Red) obtained 1986-09-29 09:33 (via the Digitized Sky Survey; limiting mag 20.5). In MPChecker no asteroids.
