Previous RA, DEC: 00:40:30.580, +41:38:52.40 (10.127417, +41.647889)
Updated RA, DEC: 00:40:30.600, +41:38:52.69 (10.1275, 41.647969)

This transient was observed on 2017 08 30.06033 by Massimo Caimmi from Valdicerro Observatory C92 - 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 at 17.9 Mag. End figures for astrometry were AR. 30.58s and DEC. 53.0" position measured from UCAC-4 reference stars catalogue.
