Paolo Campaner report the discovery of PSN (unfiltered magnitude = 18.4) on three images (limiting magnitude 20.0) obtained on August 09.0243 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.

Paolo Campaner confirm the presence of this PSN (unfiltered magnitude = 18.3) on several images (limiting magnitude 20.0) obtained on August 09.875 UT with a 0,4m reflector F/5.5 + CCD and exposure 5x75sec. at Ponte di Piave - Italy, in the course of the Italian Supernovae Search Project

2015 08 09.971

This transient was observed by J. Grzegorzek on 2015 08 09.971, using the 0.25m f/4 reflector at his JGAO observatory, Poland. 50-seconds unfiltered exposure: mag. 18.3 (ref. UCAC4). Astrometry: 19h27m37.74s +54°22'32.9". Image at http://www.jgao.pl/pgc63229.html

2015 08 13.06471

This transient was observed on 2015 08 13.06471 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. 18.8 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 37.68; 32.7 (J2000.0, mean residuals of 0.2" on both axes).

2015 08 12.163

This supernova in NGC 6801 was detected with 10 x 10 min images using a clear filter Photometry: Mag 19.00 +/- 0.43 C (V for ref; USNOA2) Astrometry: RA 19 27 37.70 Dec +54 22 32.3 These data were collected remotely by Joseph Brimacombe, Coral Towers Observatory, Cairns, Australia.
