New Comet: C/2012 C1 (McNAUGHT)

Cbet nr.3016, issued on 2012, February 11, announces the discovery of a new comet (discovery magnitude 18.8) by R. H. McNaught on CCD images obtained on February 5.5, 2012 taken with the 0.5-m Uppsala Schmidt telescope at Siding Spring. The new comet has been designated C/2012 C1 (McNAUGHT).

We performed some follow-up measurements of this object, while it was still on the neocp. Stacking of eight R-filtered exposures, 30-sec each, obtained remotely, from the Siding Spring-Faulkes Telescope South on 2012, Feb. 6.4, through a 2.0-m f/10.0 Ritchey-Chretien + CCD, shows that this object is a comet: coma about 5" in diameter, with a weak central condensation. The coma is slightly elongated toward the southwest.
