F. Ciabattari, E. Mazzoni and M. Rossi report the discovery of an apparent supernova (unfiltered magnitude = 16.3) on images (limiting magnitude 19.5) obtained on June 06.85 UT and June 7.85 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. = 12h41m50s.45, Decl. = -07°10'12".2 (equinox 2000.0, astrometry with respect to UCAC-2 stars) which is 4 arcsec west and 3 arcsec south of the centre of Galaxy PGC 42600.

This possible supernova in PGC 42600 was detected with 4 x 10 min images using a clear filter Photometry: Mag 15.96 +/- 0.19 C (V for ref; USNOA2) Astrometry: RA 12 41 50.44 Dec -07 10 12.9 These data were collected remotely by Joseph Brimacombe, Coral Towers Observatory, Cairns, Australia.

2015 06 09.86759

This transient was observed on 2015 06 09.86759 by G. Masi and P. Catalano, 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. 16.2 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 50.44; 12.4 (J2000.0, mean residuals of 0.1" on both axes).
