F. Ciabattari, E. Mazzoni and G. Petroni report the discovery of an apparent supernova (unfiltered magnitude = 17.8) on images (limiting magnitude 19.5) obtained on July 18.95 UT and July 19.92 UT with a 0.5m Newtonian telescope + CCD FLI Proline 4710 camera at Borgo a Mozzano - Italy, in the course of the Italian Supernovae Search Project. The new object is located at A.R. = 20h04m34s.85, Decl. = +12°44'16".8 (equinox 2000.0, astrometry with respect to UCAC-2 stars) which is 4 arcsec east and 7 arcsec south of the centre of Galaxy UGC 11512.

This possible supernova in UGC 11512 was detected with 11 x 10 min images using a luminance filter Photometry: Mag 18.30 +/- 0.37 C (V for ref) Astrometry: RA 20 04 34.83 Dec +12 44 17.5 These data were collected remotely by Joseph Brimacombe, Coral Towers Observatory, Cairns, Australia.

2014 07 25.82328

This transient was observed on 2014 07 25.82328 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. 18.2 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 34.84; 16.2 (J2000.0, mean residuals of 0.2" on both axes).
