This transient was observed on 2015 02 17.83483 by G. Masi, remotely using the 17"-f/6.8 robotic unit part of the Virtual Telescope Project facility, at Bellatrix Astronomical Observatory in Ceccano, Italy. 180-seconds exposures, unfiltered, show the source at mag. 17.5 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 47.61; 47.3 (J2000.0, mean residuals of 0.2" on both axes).
