L. Elenin (Lyubertsy, Russia) and I. Molotov (Moscow, Russia) confirm an apparent supernova PSN J22143782+3257187 in PGC 68367. 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. 29.3880. Object located at 22h 14m 37s.86 +/- 0".11, +32d 57' 18".1 +/- 0".12 (NOMAD) and have magnitude 16.7U (mag. limit ~19.9m). Nothing is visible at this position on the POSS and POSSII images.

MASTER-Amur 60-sec unfiltered images on 2012 Aug. 20.73 UT (7 days before the discovery images posted at TOCP) show the object at U=17.0+/-0.2. Nothing is visible at this position on 2012 Aug. 15.60 UT (limiting magnitude 18.2), implying that the outburst has occured somewhere between Aug. 15 and Aug. 20.
