F. Ciabattari, E. Mazzoni and M. Rossi report the discovery of an apparent supernova (unfiltered magnitude = 16.5) on images (limiting magnitude 19.5) obtained on May 09.06 and May 09.83 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. = 13h32m49s.11, Decl. = +41°52'15".1 (equinox 2000.0, astrometry with respect to UCAC-2 stars) which is 4 arcsec east and 4 arcsec South of the centre of Galaxy NGC 5214.

this transient was observed on 2014 05 09.86387 by Gianluca Masi, remotely using the 17"-f/6.8 corrected Dall-Kirkham 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. 16.3 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 49.05; 15.3 (J2000.0, mean residuals of 0.2" on both axes).

Simone Leonini, Siena, Italy, report the pre-discovery by P. Rosi, M. Conti, L.M. Tinjaca Ramirez, G. Guerrini, and himself of the PSN in NGC5214 (mag. about +17.5 – USNO B1) on unfiltered CCD image (limiting mag. about +19.3) taken on 2014 May. 04.99174UT at the Montarrenti Observatory in the course of an automatic survey of the Italian Supernovae Search Project. Telescope: RC D=0.53m f/8.7. Detector: U47. Astrometry: R.A. 13h32m49.08s, Decl.+41°52’14.6”- 2000.0. Nothing is visible at the position of the apparent supernova on image taken on 2014 Apr. 24.00395 (limiting mag about +19.3).
