Vladimir Lipunov reports the discovery by Sergey Shurpakov of a possible supernova (mag 16.5) on 3 unfiltered CCD images (limiting mag 18.2) obtained with the auto-detection system of the MASTER II 40-cm telescope (+ Apogee Alta U16m camera; field-of-view 2x4 square degrees) at the MASTER-Amur observatory (see website URL http://observ.pereplet.ru) on 2013-11-28.88726 UT. The new object is located at R.A. = 13h22m48s.38, Decl. = +33d30'20".7 (equinox 2000.0), which is 7" east and 11" south of the center of PGC 2033541.

L. Elenin (Lyubertsy, Russia) and I. Molotov (Moscow, Russia) confirm an apparent supernova PSN J13224838+3330207. Object visible on 3x150sec images remotely taken at ISON-NM Observatory (Mayhill, NM, USA) with 0.4-m f/3 telescope + CCD (KAF09000) on Nov. 29.4754, 2013. Object located at 13h 22m 48s.36 +/- 0".12, 33d 30' 21".4 +/- 0".16 (UCAC-4) with magnitude 17.1R (mag. limit ~19.4m). Nothing is visible at this position on the POSS and POSSII images.

This transient was observed on 2013 12 05.124 by Gianluca Masi, Francesca Nocentini and Patrick Schmeer, remotely using the 17"-f/6.8 robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. 120-seconds exposures, unfiltered, show the source at mag. 17.3 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 48.35s; 21.6" (J2000.0, mean residuals of 0.2" on both axes).
