L. Elenin (Lyubertsy, Russia) and I. Molotov (Moscow, Russia) confirm an apparent supernova PSN J09310887+4623054 in UGC 05066. Object visible on 2x150sec images remotely taken at ISON-NM Observatory (Mayhill, NM, USA) with 0.4-m f/3 telescope + CCD (KAF09000) on Dec. 01.4509, 2013. Object located at 09h 31m 08s.81 +/- 0".10, 46d 23' 04".9 +/- 0".11 (UCAC-4) with magnitude 16.9R (mag. limit ~18.9R). Nothing is visible at this position on the POSS and POSSII images.

Mag.: 16.8(V) R.A.: 09 31 08.84; Decl.: +46 23 05.4 (2000.0). Reference: PPMXL Observer: Massimiliano Martignoni - Observatory: Stazione Astronomica Betelgeuse (B75), Magnago, Italy Telescope: Schmidt-Cassegrain 0.25m-f/10.0 - CCD: KAF0261E
2013 12 04.945
This transient was observed on 2013 12 04.945 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. 16.2 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 08.83s; 05.3" (J2000.0, mean residuals of 0.2" on both axes).
