(60558) 2000 EC98
     Y.-J. Choi and P. R. Weissman, Jet Propulsion Laboratory,
report the detection of a cometary coma on B, V, R, and I
images of the Centaur object (60558) taken on 2005 Dec. 30.50
UT with the Palomar 5-m reflector (+ Large Format Camera);
the total apparent magnitude was R = 17.5 and the coma extends
about 20" from the nuclear condensation in a 600-second R-band
exposure.  Confirming images of the object's cometary nature
were obtained by Choi on 2006 Jan. 1, and D. Polishook confirmed
the coma on images obtained at Wise Observatory on Jan. 2.  The
object was discovered by Spacewatch (discovery observation below
from MPEC 2000-E64 and MPS 11487).

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