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 04.1243

This transient was observed by Paolo Campaner (unfiltered magnitude = 18.1) on several images (limiting magnitude 20.0) obtained on September 04.1243 UT with a 0,4m reflector F/5.5 + CCD and exposure 10x75sec. at Ponte di Piave - Italy, in the course of the Italian Supernovae Search Project

2015 09 07.382

This possible supernova in UGC 3460 was detected with 21 x 5 min images using a clear filter Photometry: Mag 17.63 +/- 0.27 C (V for ref; USNOA2) Astrometry: RA 06 28 03.61 Dec +74 18 34.2 These data were collected remotely by Joseph Brimacombe, Coral Towers Observatory, Cairns, Australia.

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.
