COMET C/2011 Q3 (McNAUGHT)
     R. H. McNaught reports his discovery of another comet on CCD images taken
with the 0.5-m Uppsala Schmidt telescope at Siding Spring (discovery
observation tabulated below), the object appearing elongated with a hint of a
tail 0'.3 long in p.a. 240 deg.  His follow-up images on Aug. 30.6 UT confirm
the cometary appearance, with a tail 0'.7 long fanned between p.a. 240 and
255 deg.

     2011 UT             R.A. (2000) Decl.       Mag.   Observer
     Aug. 29.74083    0 16 50.17   - 5 53 42.4   18.5   McNaught

The available astrometry, the following preliminary parabolic orbital elements
by G. V. Williams, and an ephemeris appear on MPEC 2011-R01.  It is likely
that this comet is of short period.

     T = 2012 Feb.  4.808 TT          Peri. =  46.106
                                      Node  =  21.651   2000.0
     q = 1.61165 AU                   Incl. =   9.011
