We managed to perform some optical follow-up of the OT reported by Gorbovskoy et al. ( ATel #7381 ), remotely using the 17" robotic unit part of the Virtual Telescope Project, Italy.
A series of 120-seconds exposure, unfiltered, started at 13.8934 Apr. 2015, clearly shows the source mentioned by Gorbovskoy et al. (our astrometry end figures: 41.97"; 27.7"; J2000.0, based on UCAC-4).
We estimated a magnitude of 18.0 (using R mags from UCAC-4 for the reference stars, the QE of our CCD devive peaking in the red part of the spectrum).
