PSN J12054713+2025026   2015 04 13.055 *  12 05 47.13 +20 25 02.6  18.5 U    1E   8S  P1626773  P 2



2015 04 15.82523

This transient was observed on 2015 04 15.82523 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. 18.2 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 47.18; 02.4 (J2000.0, mean residuals of 0.1" on both axes).
