Andrew Howell, Curtis McCully, Stefano ValentiLCOGT SN-KPSN Ia0.005LCOGT SN-KPUsing SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find a good fit to the several normal Type Ia supernovae around a week before maximum light at redshifts consistent with that of the proposed host galaxy (z=0.005; de Vaucouleurs et al. 1991, Third Reference Catalogue of Bright Galaxies, version 3.9, via NED).

Previous RA, DEC: 12:08:06.800, +65:10:38.24 (182.028333, +65.177289)
Updated RA, DEC: 12:08:06.800, +65:10:37.80 (182.028333, 65.177167)

This transient was detect on 2016 05 29.824 from C92 - Valdicerro Observatory, Loreto (AN) Italy using 0.24-m f/6.5 SCT + CCD Atik 314L in the course of Italian Supernovae Search Project (ISSP). Stack of 15 unfiltered b2x2 frames x 30sec unguided exposures, show the source 14.4 Mag. The astrometry were AR. 06.79s DEC. 37.8" measured from UCAC-4 reference stars catalogue.

This SN candidate was also independently detected by ASAS-SN "Brutus" in Hawaii
