Paolo Campaner report the discovery of PSN (unfiltered magnitude = 18.3) on three images (limiting magnitude 20.0) obtained on September 02.1000 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 09 03.01
This transient was observed on 2015 09 03.00675 by M.Caimmi from C92 - Valdicerro Observatory in the course of the Italian Supernovae Search Project (ISSP) using 0.24-m f/6.5 SCT - CCD Atik 314L. Stack of 15 unfiltered b1x1 frames x 240sec guiding exposures, show the source at 18.2 Mag. End figures for astrometry were AR. 03,74s DEC. 34,1" position measured from reference stars UCAC-4 catalogue.

2015 09 12.90366
This transient was observed on 2015 09 12.90366 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. 17.0 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 03.57; 34.0 (J2000.0, mean residuals of 0.2" on both axes).
2015 09 18.90243
This transient was observed on 2015 09 18.90243 UT by Zhijian Xu and Xing Gao, using an unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=356-mm @f/6.9 ), in Xingming Observation Sky Survey(C42). 60-seconds exposures, show the source at mag. 17.7 U (reference stars from UCAC-4), with position end figures 03s.56, 34".3.
