We performed some follow-up of this object remotely through a 0.43-m f/6.8 astrograph + CCD of ITelescope network (MPC Code Q62 - Siding Spring, AU). On our images taken on July 27.7, 2013 we can confirm the presence of an optical counterpart with R-filtered CCD magnitude 13.0 and V-filtered CCD magnitude 12.6 at coordinates: R.A. = 01 36 48.20, Decl.= +15 45 31.0 (equinox 2000.0; UCAC-3 catalogue reference stars).

2013 07 28.0277

This transient was observed by Gianluca Masi and Francesca Nocentini, remotely using the 14" robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. Unfiltered images show the source at mag. 12.8 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 48.18s; 30.9" (J2000.0, mean residuals of 0.1" on both axes).
