COMET P/2014 O1 = P/2000 QJ46 (LINEAR)
     M. Micheli reports the recovery of comet P/2000 QJ46 (cf. IAUC 8622) on
images taken by D. Abreu with the European Space Agency's Optical Ground
Station 1.0-m f/4.4 reflector at Tenerife; measurers assisting Micheli
included M. Busch, F. Hormuth, D. Koschny, E. Schwab, and A. Knoefel.  The
following astrometry observations were provided:

The indicated correction to the prediction by B. G. Marsden on MPC 75735 is
Delta(T) = -0.24 day.  The following linked orbital elements by G. V. Williams
are form 31 observations spanning 2000 Aug. 24-2014 July 26 (mean residual
0".7):
