Paolo Campaner report the discovery of PSN (unfiltered magnitude = 18.7) on three images (limiting magnitude 20.0) obtained on August 13.0812 UT with a 0,4m reflector F/5.5 + CCD and exposure 3x75sec. at Ponte di Piave - Italy, in the course of the Italian Supernovae Search Project.




2015 08 13.97154

This transient was observed on 2015 08 13.97154 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. 18.6 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 09.87; 53.0 (J2000.0, mean residuals of 0.1" on both axes).
