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:

     2014 UT             R.A. (2000) Decl.       Mag.   Observer

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):

                    Epoch = 2014 Dec.  9.0 TT
     T = 2014 Dec. 20.23033 TT        Peri. = 222.14923
     e = 0.6743202                    Node  = 158.08939 2000.0
     q = 1.8891541 AU                 Incl. =   4.42705
