This transient was observed on 2014 01 06.037 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. 18.7 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 55.93s; 11.9" (J2000.0, mean residuals of 0.2" on both axes).
