2015 08 13.09428

This transient was observed on 2015 08 13.09428 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. 120-seconds exposures, unfiltered, show the source at mag. 18.9 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 21.93; 40.7 (J2000.0, mean residuals of 0.2" on both axes).
