V. Lipunov (SAI MSU) reports the discovery by S. Shurpakov of a possible supernova (mag. 17.2) on two unfiltered survey images (limiting mag 18.6) taken on Jan. 25.1193 UT with the MASTER-Kislovodsk robotic telescope (0.40-m f/2.5 reflector + 4Kx4K CCD). The new object is located at R.A. = 17h14m27s.91, Decl. = +23o03'33".8 (equinox 2000.0).The OT unfiltered magnitude is 17.2m (limit 18.6m). The OT is seen in 2 images. There is no minor planet at this place. We have reference image without OT on 2011-04-15.04177 UT with unfiltered magnitude limit 19.9m. (see also ATel #4761).

L. Elenin (Lyubertsy, Russia) and I. Molotov (Moscow, Russia) confirm an apparent supernova PSN J17142791+2303338. 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 Mar. 28.3459, 2013. Object located at 17h 14m 27s.96 +/- 0".11, +23d 03' 33".9 +/- 0".13 (UCAC-4) with magnitude 18.6U (mag. limit ~19.0m). Nothing is visible at this position on the POSS and POSSII images.
