Possible novae in M31 discovered by Stanislav Korotkiy and Leonid Elenin on images, obtained on 2011 Oct 22.4596UT using 0.45-m f/2.8 astrograph + unfiltered CCD under the limiting magnitude = 20.0R at ISON-NM Observatory, Mayhill, USA (MPC COD H15). Mag=18.6C +-0.3 mag, astrometry: RA=00 45 28.85; DEC=+41 54 09.4 (UCAC3, J2000, accuracy of 0.3") . Offset on discovery images: 1834"E and 2282"N. Three images caught this object. Image taken on Oct. 21.3514UT 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). In SIMBAD object RX J0045.4+4154 located at a distance 3.79 asec. No object in: MPChecker, VSX AAVSO and SDSS-III. Image URL: http://www.astroalert.su/files/pnv_j00452885_4154094.png
