L. Elenin (Lyubertsy, Russia) and I. Molotov (Moscow, Russia) confirm an apparent supernova PSN J02263653+1208555 in NGC 927. Object visible on 3x300sec images remotely taken at ISON-NM Observatory (Mayhill, NM, USA) with 0.45-m f/2.8 telescope + CCD (KAF09000) on Aug. 29.2744. Object located at 02h 26m 36s.53 +/- 0".11, +12d 08' 55".6 +/- 0".11 (NOMAD) and have magnitude about 16.4U (mag. limit ~19.4m). Nothing is visible at this position on the POSS and POSSII images.

Simone Leonini, Siena, Italy, report the discovery by S. Leonini, G. Guerrini, P. Rosi and L.M. Tinjaca Ramirez of a PSN in NGC927 (mag. about +17.6CR +/-0.06 – USNO A2) on unfiltered CCD image (limiting mag. about +18.4) taken on 2012 August 27.02828 UT at the Montarrenti Observatory(C88) in the course of an automatic survey of the Italian Supernovae Search Project. Telescope/Detector: RC 0.53m f/8.7 + U47; Astrometry: R.A. 02h26m36.53s, Decl.+12degrees08arcmin55.5arcsec. - equinox 2000.0). Nothing is visible at this position on POSS images and our past images including one on 2012 July 27 (limiting mag. about +19.0). No known minor planets are marked in that position for the time of our observation. Discovery image: http://www.astrofilisenesi.it/public/Sne/Uploads/PSN_in_NGC0927.jpg
