     An apparently asteroidal object discovered by Korado Korlevic
at Visnjan with a 0.41-m f/4.3 reflector + CCD (the discovery
observation below was first published on MPS 7912) was indicated on
some of his December images to be possibly "fuzzy", and cometary
nature has been confirmed by C. Hergenrother and S. Larson, Lunar
and Planetary Laboratory, who found a 13" coma elongated in p.a. 80
deg on a 600-s co-added R-band exposure taken on 2000 Feb. 7.25 UT
with the 1.54-m Catalina reflector.

     1999 UT             R.A. (2000) Decl.        m2
     Nov. 28.94427    4 34 56.58   +24 51 51.8   17.9

     Additional observations and orbital elements (T = 2000 Feb.
15.2 TT, q = 3.17 AU, i = 2.98 deg, P = 9.97 yr) appear on MPEC

     Another apparently asteroidal object was reported by LINEAR
and posted on the NEO Confirmation Page.  This object has the orbit
of a centaur and was noted as appearing perhaps slightly diffuse
(P. Kusnirak, Ondrejov, 0.65-m reflector, Feb. 10) and 'soft' and
slightly larger than star images (D. Balam, Victoria, 1.82-m
reflector, Feb. 11).  Astrometry and orbital elements (T = 2000
June 24.6 TT, q = 6.82 AU, i = 15.9 deg, P = 77 yr) appear on MPEC

     2000 UT             R.A. (2000) Decl.        m2
     Jan. 29.24832    8 08 15.43   +37 03 04.0   19.4

     Yet another apparently asteroidal LINEAR object that was
posted on the NEO Confirmation Page was noted to have a 15"-16"
tail toward the north-northwest on Feb. 12 by J. G. Ries, McDonald
Observatory (0.76-m reflector).  Astrometry and parabolic orbital
elements (T = 2001 June 18.6 TT, q = 3.13 AU, i = 49.2 deg) appear
on MPEC 2000-D10.

     2000 UT             R.A. (2000) Decl.        m2
