COMET P/2014 K1 = P/2001 BB_50 (LINEAR-NEAT)
     R. Wainscoat reports the accidental recovery of comet P/2001 BB_50 (cf.
IAUC 7601) on CCD images obtained with the Pan-STARRS 1.8-m Ritchey-Chretien
telescope at Haleakala on May 17; the object appeared obviously cometary in
the w-band exposures.  From this, G. V. Williams was able to link their
observations to P/2001 BB_50 and then found earlier confirming observations in
the Minor Planet Center's archive from Mar. 1 obtained by A. Wulff (measured
by J. Jahn) with the SATINO Remote Observatory's 0.60-m f/3.2 reflector at
Haute Provence.  Available astrometry:

The indicated correct to the prediction by S. Nakano in the ICQ 2003 Comet
Handbook (p. H12) is Delta(T) = -1.74 day.  The following linked orbital
elements by Williams (from 99 observations spanning 2001 Jan. 21-2014 May
17; mean residual 0".6) and an ephemeris appear on MPEC 2014-K21.
