2014 03 23.965
This transient was observed on 2014 03 23.965 by Gianluca Masi, Francesca Nocentini and Patrick Schmeer, remotely using the 17"-f/6.8 corrected Dall-Kirkham robotic unit part of the Virtual Telescope Project facility, at Bellatrix Astronomical Observatory in Ceccano, Italy. 120-seconds exposures, unfiltered, show the source at mag. 17.4 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 43.17; 56.8 (J2000.0, mean residuals of 0.2" on both axes).

L. Elenin (Lyubertsy, Russia) and I. Molotov (Moscow, Russia) confirm an apparent supernova PSN J10404316+3556581 in PGC 2072488. Object visible on 3x150sec images remotely taken at ISON-NM Observatory (Mayhill, NM, USA) with 0.4-m f/3 telescope + CCD (KAF09000) on Mar. 24.2396, 2014. Object located at 10h 40m 43s.14 +/- 0".09, +35d 56' 58".7 +/- 0".16 (UCAC-4) with magnitude 17.7R (mag. limit ~19.7m). Nothing is visible at this position on POSS and POSSII images.
