2015 01 26.96325

This transient was observed on 2015 01 26.96325 by G. Masi and P. Catalano, 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. 19.0 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 13.20; 21.8 (J2000.0, mean residuals of 0.2" on both axes).
