We performed some follow-up measurements of this object, while it was still on the neocp. Stacking of ten R-filtered exposures, 60-sec each, obtained remotely, from the Siding Spring-Faulkes Telescope South on 2012, Feb. 16.6, through a 2.0-m f/10.0 Ritchey-Chretien + CCD, shows that this object is a comet: faint fan-shaped tail, nearly 6-arcsec long in PA 284.
