COMET P/2014 D1 = P/2008 J2 (BESHORE)
     D. T. Durig, University of the South, Sewanee, TN, USA, reports the
recovery of comet P/2008 J2 (cf. IAUCs 8941, 8942, 8944) on CCD images taken
by M. R. Lebow, J. F. North, A. M. Kops, B. B. Goodson, and himself with a
0.3-m f/2.5 Schmidt-Cassegrain reflector (nothing stated about the object's
appearance).  G. V. Williams subsequently identified pre-recovery observations
from Jan. 2 obtained by E. J. Christensen at Mount Lemmon.  The available
astrometry is tabulated below:

The correction to the prediction by Williams on MPC 75733 is Delta(T) =
-0.3 day.  Williams provides the following linked orbital elements from
455 observations spanning 2008 May 6-2014 Feb. 28 (mean residual 0".5).
An ephemeris is included also on MPEC 2014-D59.

                    Epoch = 2014 Aug. 11.0 TT
     T = 2014 Aug. 29.97944 TT        Peri. = 132.20118
     e = 0.3187361                    Node  =  97.70889 2000.0
     q = 2.3462218 AU                 Incl. =  10.32516
       a =  3.4439253 AU   n = 0.15421389   P =   6.39 years
