IAU Circular nr.9071, issued on 2009, Sep. 10, announces the discovery of a new comet by R. H. McNaught, named C/2009 R1 (McNAUGHT). This comet may reach magnitude 5 at the end of June 2010, but the elongation will be very small (only 18 degree on June 27, 2010) and so the observing conditions.

McNaught has just discovered his 50th comet. He spotted it, as he does most often these days, on images taken with the 20-inch (0.5-meter) Uppsala Schmidt telescope at Siding Spring Observatory in Australia.

IAUC nr. 9075, issued on 2009 Sept. 24th, announces the discovery of another comet by Robert McNaught, named P/2009 S2.

The comet is now around magnitude 7.5 and it will be a nice binocular object. Throughout this apparition it will be low in the east or northeast when dawn begins to brighten.
