COMET C/2006 K3 (McNAUGHT)
     R. H. McNaught reports his discovery of yet another comet on
Uppsala Schmidt telescope images (discovery observation tabulated
below); the new object appeared diffuse with a 11" coma, extended
20" to the southeast; deeper exposures on May 22.37 UT show a well-
condensed head with a 20" tail in p.a. 135 deg.

     2006 UT             R.A. (2000) Decl.       Mag.
     May  22.34471    6 50 29.50   -63 44 05.7   17.2

The available astrometry, the following preliminary parabolic
orbital elements, and an ephemeris appear on MPEC 2006-K40.

     T = 2007 Mar. 13.340 TT          Peri. = 327.144
                                      Node  =  49.694   2000.0
     q = 2.54087 AU                   Incl. =  92.714


COMET C/2006 K4 (NEAT)
     An apparently asteroidal object reported by the NEAT project
from their CCD images taken with the 1.2-m Schmidt telescope at
Palomar (discovery observation tabulated below) has been found
cometary (following posting on the 'NEO Confirmation Page') by J.
Young at Table Mountain (0.61-m f/16 Cassegrain reflector), who
noted a round 5" coma with no central condensation and no tail on
his images from May 24.4 UT.

     2006 UT             R.A. (2000) Decl.       Mag.

The available astrometry, the following preliminary parabolic
orbital elements, and an ephemeris appear on MPEC 2006-K41.

     T = 2007 Dec.  3.052 TT          Peri. = 233.246
                                      Node  = 116.524   2000.0

COMET 73P/SCHWASSMANN-WACHMANN
     Further to IAUC 8709, additional components have been
designated:  'BQ' on MPEC 2006-J31, and 'BR' and 'BS' on MPEC
2006-K18.
