This transient was observed on 2015 12 19.81675 by G. Masi, remotely using the 17"-f/6.8 robotic unit at Bellatrix Astronomical Observatory in Ceccano, Italy. 120-seconds exposures, unfiltered, show the source at mag. 18.3 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 48.23; 44.4 (J2000.0, mean residuals of 0.2" on both axes).

PSN J07484828+5435434 2015 12 20.9196 This transient was observed on 2015 12 20.91959 by M.Caimmi from C92 - Valdicerro Observatory, Loreto (AN) Italy using 0.24-m f/6.5 SCT + CCD Atik 314L in the course Italian Supernovae Search Project (ISSP). Stack of 15 unfiltered b2x2 frames x 30sec unguided exposures, show the source increase at 17.7 Mag. End figures for astrometry were AR. 48.23s DEC. 44.5" position measured from UCAC-4 reference stars catalogue.
