We performed some follow-up measurements of this object, while it was still on the neocp, with "Faulkes-Telescope North" on September 08, 2011.
Stacking of 6 R-filtered exposures, 60-sec each, obtained remotely, from the Haleakala-Faulkes Telescope North on 2011, September 8.4, through a 2.0-m f/10.0 Ritchey-Chretien + CCD, shows that this object is a comet: sharp central condensation, coma nearly 4-arcsec in diameter elongated toward southwest, broad tail at least 7-arcsec long toward PA 252.
M.P.E.C. 2011-R34 assignes the following preliminary orbital elements to comet P/2011 R3: T 2011 Aug. 23.36; e= 0.26; Peri. =189.68; q = 3.56 AU; Incl.= 18.04
