2014 02 13.003

This transient was observed on 2014 02 13.003 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. 18.2 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 56.77; 27.5 (J2000.0, mean residuals of 0.2" on both axes).
