2013 09 16.760

This transient was observed on 2013 09 16.760 by Gianluca Masi, Francesca Nocentini and Patrick Schmeer, remotely using the 17" robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. Unfiltered images show a source at mag. 16.6 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 00.21s 51.7" (J2000.0, mean residuals of 0.15" on both axes).
