This transient was observed on 2014 02 12.976 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: 50.33; 03.4 (J2000.0, mean residuals of 0.2" on both axes).
