2015 03 30.82737

This transient was observed on 2015 03 30.82737 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: 15.96; 38.4 (J2000.0, mean residuals of 0.1" on both axes).
