Possible novae in M31 discovered by Stanislav Korotkiy and Vladimir Gerke on images, obtained on 2011 Oct 06.7239UT using 0.40-m f/8 reflector + unfiltered CCD (STL-11000M) under the limiting magnitude = 20.0R at Ka-Dar Observatory, TAU Station, Nizhny Arkhyz, Russia (MPC COD C32). Mag=18.7C +-0.3 mag, astrometry: RA=00 43 26.30; DEC=+41 11 14.8 (UCAC3, J2000, accuracy of 0.3"). Offset on discovery images: 475"E and 294"S. Three images caught this object. Image taken on Sep. 14.9UT does not detect the object (limiting mag 20.0R). Nothing is visible at this position on a Palomar Sky Survey DSS image obtained on 1986-11-27 (via the Digitized Sky Survey; limiting red mag 20.5). No object in: MPChecker, VSX AAVSO and SIMBAD.

Inspect of CCD R-band images obtained by J. Gorosabel and P. Kubanek using the 1.23-m telescope at Calar Alto and processed by K. Hornoch show no object down to R = 20.6 mag. Additional imaging on Oct. 10.139 UT with the same instrumentation show no object down to R = 20.8 mag. It suggest that the object is not real (it is very probably flaw on discovery images). K.
