Trans-Neptunian Object 2012 DR30

M.P.E.C. 2012-D67, issued on 2012, February 26, announces the discovery of a new Trans-Neptunian Object (discovery magnitude 18.7) by R. H. McNaught with 0.5-m Uppsala Schmidt + CCD at Siding Spring on February 22, 2012. The new object has been designated 2012 DR30.

We performed some follow-up measurements of this object, while it was still on the neocp. Stacking of six R-filtered exposures, 60-sec each, obtained remotely, from the Siding Spring-Faulkes Telescope South on 2012, Feb. 23.5, through a 2.0-m f/10.0 Ritchey-Chretien + CCD, shows that the object has stellar aspect.
