L. Elenin (Lyubertsy, Russia) and I. Molotov (Moscow, Russia) confirm an apparent supernova PSN J01584281+0820378 in NGC 766. Object visible on 3x150sec images remotely taken at ISON-NM Observatory (Mayhill, NM, USA) with 0.45-m f/2.8 telescope + CCD (KAF09000) on Aug. 06.4609, 2013. Object located at 01h 58m 42s.75 +/- 0".16, +08d 20' 39".9 +/- 0".14 (UCAC-4) with magnitude 16.8U (mag. limit ~19.1m). Nothing is visible at this position on the POSS and POSSII images.

2013 09 07.917

This transient was observed on 2013 09 07.917 by Gianluca Masi, Francesca Nocentini and Patrick Schmeer, remotely using the 17" robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. Unfiltered images show a source at mag. 17.4 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 42.75s; 39.4" (J2000.0, mean residuals of 0.15" on both axes).
