2015 07 11.0173

Massimo Caimmi report the discovery of an apparent supernova at 2015 07 11.01735 on image obtained with SC Telescope 0.24-m f/6.5 and CCD Atik 314L (exposure 15 frame x 15sec) from Valdicerro Observatory (C92) - Loreto (AN) Italy, in the course of the Italian Supernovae Search Project (ISSP). The new object is located at A.R. = 20h43m53s.14, Decl. = +12°30'30".4, astrometry with respect to UCAC-4 stars which is 7 arcsec West and 14 arcsec South of the centre of Galaxy NGC6956. First image of this discovery is available from this link: http://www.oav.name/public/PSN_J20435314+1230304_20150711_frame.jpg

R.Belligoli, F.Castellani and C.Marangoni from Monte Baldo Astronomic Observatory Ferrara Monte Baldo Verona Italy , in the course of the ISSP Italian Supernovae Search Project, confirme this transient in three 60s images Luminance Filter taken on 2015 7 11,39235 by Remote Observatory in Auberry California USA - MPC U69 (Itelescope) Planewave 24" (0.61m) CDK focal lenght 2962mm f/6.5 . By Astrometrica measurements: RA20h43m42.26s DEC+12°28'44.6". Confirmation image at http://www.osservatoriomontebaldo.it/uploads/ISSP/NGC6956-PSN-J20435314+1230304.jpg



2015 07 11.89976

This transient was observed on 2015 07 11.89976 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. 17.7 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 53.12; 30.4 (J2000.0, mean residuals of 0.1" on both axes).



2015 07 12.871

This transient was observed by M.Caimmi on 2015 07 12.87098 using SCT 0.24-m f/6.5 and CCD Atik 314L. Stack of 30 unfiltered frames x 300sec exposure, shows increase luminosity at 17.3 Mag. End figures for astrometry were AR=53s.19s - DEC=30".4 position measured from reference stars catalogue UCAC-4.
