L. Elenin (Lyubertsy, Russia) report about discovery of an apparent supernova in PGC42095477 galaxy. Object visible on four 240-sec images taken with 15 minutes intervals. Images remotely taken at ISON-NM Observatory (Mayhill, NM, USA) with 0.45-m f/2.8 telescope + CCD (KAF09000) on Nov. 18.2298. The new object is located at 06h 58m 07".68 +/- 0".1, +37d 13' 11".7 +/- 0".1 (UCAC3), which is about 17" west and 6" north from the center of PGC42095477 galaxy. And have magnitude about 18.7U (mag. limit ~20.2m). Nothing is visible at this position on the POSS and POSSII images taken in eight epochs. This object not a known Solar System object.
