COMET P/2014 U1 = P/1997 G1 (MONTANI)
     G. V. Williams has identified astrometry of an apparently asteroidal
object found on Spacewatch CCD images obtained at Kitt Peak by T. H. Bressi
(Oct. 21) and A. F. Tubbiolo (Oct. 25) with comet P/1997 G1 (cf. IAUCs 6622,
6624, 6670); Williams then found additional Spacewatch observations obtained
by Tubbiolo and Bressi on Oct. 13.  The new astrometric observations are
tabulated below.

The indicated correction to orbital elements by Williams on MPC 84327 is
Delta(T) = -1.15 days; the indicated correction to orbital elements by S.
Nakano in the ICQ's 2014 Comet Handbook is Delta(T) = -1.35 days.  The
following linked orbital elements by Williams are from 84 observations
spanning 1997 Apr. 9-2014 Oct. 25 (mean residual 0".6):
