COMET C/2002 J5 (LINEAR)
     An apparently asteroidal object discovered by LINEAR
(discovery observation below) has been found to be slightly diffuse
with a coma diameter of about 10" on CCD images taken by M. Tichy
and M. Kocer with the 1.06-m reflector at Klet on May 16.0 UT.

     2002 UT             R.A. (2000) Decl.        m2
     May  15.38149   20 16 07.57   + 8 44 51.5   18.2

The available astrometry (including prediscovery observations from
Aug. 2001) and the following orbital elements appear on MPEC
2002-K16.

COMET C/2002 K2 (LINEAR)
     Another apparently asteroidal LINEAR discovery has also been
found to be cometary on Klet CCD images that show a compact coma of
diameter about 7"-8" on May 16.9 and 18.0 UT.

     2002 UT             R.A. (2000) Decl.        m2
     May  16.36948   18 06 11.35   +12 03 22.6   18.2

The available astrometry and the following very uncertain parabolic
orbital elements appear on MPEC 2002-K18.

     T = 2002 Sept.29.407 TT          Peri. =  58.671
                                      Node  = 296.557   2000.0

COMET C/2002 K1 (NEAT)
     Additional astrometry (cf. IAUC 7902) and the following
preliminary parabolic orbital elements appear on MPEC 2002-K17.

     T = 2002 Apr. 30.011 TT          Peri. = 353.116
                                      Node  = 280.643   2000.0
     q = 3.24338 AU                   Incl. =  88.222
