AT 2016gxp follow-up

This transient was observed on 2016 10 07.83538 by M.Caimmi 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 increase at 16.6 Mag. End figures for astrometry were AR. 34.58s DEC. 08.3" position measured from UCAC-4 reference stars catalogue.
