GIANCARLO CORTINI (Monte Maggiore Observatory-Predappio-ITALY) reports the discovery of a possible supernova in NGC 3079 by 0.35m. Sch.-Cass. F/5.5 + SXVR-H9 CCD camera on several unfiltered images taken on 2013/07/13.86 (U.T.),90 sec. exposure, mag. about+15.5,limit mag. about+ 18.5; the new object is located at: R.A. 10 01 56.83, DECL.+55 41 44.05(2000.0) wich is : 56 arcsec N and 14 arcsec. W from the centre of the parent galaxy. My past images of the same field taken on 2013/02/28.75 and 2013/04/14.90 showed nothing at that position (limit mag.+ 19.0) and it doesn't appear on P.O.S.S. II red and blue plates. No known minor planet is marked in that position for the time of the discovery.

This possible supernova in NGC 3079 was detected with 26 x 0.75 min images using a luminance filter Photometry: Mag 15.07 +/- 0.23 L (V for ref) Astrometry: RA 10 01 56.70 Dec +55 41 44.3 These data were collected remotely by Joseph Brimacombe, Cairns, Australia.

This transient was observed by Gianluca Masi and Francesca Nocentini, remotely using the 17" robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. Unfiltered images show the source at mag. 15.4 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 56.73s; 44.4" (J2000.0, mean residuals of 0.2" on both axes)

A low-res spectrum, with a 100 lines/mm grating and a resolution of 33.5 angstrom/pixel (9 micron) was observed by Gianluca Masi and Francesca Nocentini, remotely using the 14" robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. While relatively faint and with the source at about 27 deg above the horizon, the spectrum shows an emission at the H-alpha wavelength, suggesting a type II supernova. Further spectroscopy is urged.

This object was observed by Federica Luppi and Luca Buzzi from Schiaparelli Observatory, Varese, Italy. In a stack of images totalling 5 minutes of unfiltered exposure time, the object has position end figures 56s.72, 44".4 and magnitude 15.4.
