COMET P/2014 L1 = P/2003 U3 (NEAT)
     Erwin Schwab reports the recovery of comet P/2003 U3 (cf. IAUC 8230) on
CCD images obtained by P. Ruiz with a 1.0-m f/4.4 reflector at the European
Space Agency's Optical Ground Station, Tenerife (with measurement assistance
stated also by D. Koschny, M. Micheli, A. Knoefel, and M. Busch); the comet
showed a coma and a tail 15"-20" long in p.a. 250 deg.

The indicated correction to the prediction by G. V. Williams on MPC 75734 is
Delta(T) = -1.80 days; the indicated correction to the prediction by S. Nakano
in the ICQ's 2013 Comet Handbook is Delta(T) = -1.60 days.  The following
linked orbital elements by Williams (from 124 observations spanning 2003 Oct.
17-2014 June 2; mean residual 0".6) and an ephemeris appear on MPEC 2014-L12.
