COMET C/2008 R3 (LINEAR)
     An apparently asteroidal object discovered by the LINEAR
survey (and posted on the Minor Planet Center's 'NEOCP' webpage)
has been found to show cometary appearance by other astrometric CCD
observers.  E. Pettarin (Farra d'Isonzo, Italy, 0.40-m f/4.5
reflector, Sept. 7.9 UT) writes that, in a star-rich field, the
comet shows a 20" tail in p.a. 130 deg.  R. Holmes (Charleston, IL,
U.S.A., 0.81-m f/4 astrograph, Sept. 8.1) notes a diffuse,
elongated shape with coma diameter 13".3.  G. Hug (Scranton, KS,
U.S.A., 0.56-m reflector, Sept. 8.14-8.15) finds a short, diffuse
extension in p.a. about 130 deg.  J. Young (Table Mountain 0.61-m
f/16 Cassegrain reflector, Sept. 8.3) reports an 8" round, bright
coma of mag 17.5 and a poorly defined broad tail of length 16" in
p.a. 125-145 deg.  P. Camilleri, G. Sostero, and E. Guido (remotely
using a 0.30-m f/5.8 reflector at Trunkey, N.S.W., Australia, Sept.
8.44-8.48) find that nine co-added 120-s unfiltered exposures
reveal a coma that is about 12" in diameter.

     2008 UT             R.A. (2000) Decl.       Mag.

orbital elements, and an ephemeris appear on MPEC 2008-R51.
