The object was discovered on October,31 2011 by 704 Lincoln Laboratory ETS, New Mexico
On my images I couldn't detect any cometary feature. But my assumption, that the object could be a comet, was confirmed on December,29 2011
with  CBET 2960 (...if you have access to the CBAT Computer Service CS) and MPEC 2011-Y51

With an hyperbolic eccentricity of e=1.0007164 the comet is just visiting the inner Solar system for it's first time.
