Mario Bombardini and Mirco Villi (Urania Lamonia Observatory-Faenza-Italy) report the discovery of a possible supernova in UGC 9267 with a 0,35 mt. Sch.-Cass. f/5.0 + Sbig ST9 CCD camera on several unfiltered images taken on July 15,86 UT, 60 sec. exp., at mag. 16,0, limit mag. 19,0. The new object is located at RA14h27m49s, DECL +11°33’40” (J2000.0) which is 15” W and 7” N from the galaxy’s centre. Previous images of the galaxy taken on May 20, 2014 show nothing at that position, also in POSS II red and blue plates. No know minor planets are in that area during discovery time.

This object appears on an image taken by E. Conseil with Slooh Space robotic telescope T2 (Mt Teide, Canary Islands). Primary instrument : 0.35 meter f/11 Schmidt-Cassegrain. MagR ~16.1 Image available at https://www.flickr.com/photos/econseil/14659342556/

2014 07 19.81653

This transient was observed on 2014 07 19.81653 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. 60-seconds exposures, unfiltered, show the source at mag. 16.3 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 48.57; 42.4 (J2000.0, mean residuals of 0.2" on both axes).

2014 07 19.853

Several low resolution spectra of this transient were obtained on 2014 07 19.853 by G. Masi, remotely using the 14" robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. 9, 300-seconds images were taken using a 100 lines/mm grating, with a dispersion of 34.5 angstroms/pixel. They were co-added and the resulting image shows Si II absorption around 6270 angstroms, suggesting this is a type Ia supernova. Assuming a recessional velocity of 7433 km/s for the host galaxy (UGC 09267, via NED), an expansion velocity of 11200 km/s is derived from the minimum of the Si II 6350-angstrom line.
