COMET P/2012 WX_32 = 1931 AN = 2003 WZ_141 (TOMBAUGH-TENAGRA)
Syuichi Nakano, Japan, reports on CBET 3342 identification of Comet
P/2012 WX_32 (found by Schwartz and Holvorem on 2012 Nov 27), with an
apparently asteroidal object discovered by the LINEAR survey on 2003
Nov. 21 and 23 (= 2003 WZ_141) and with the comet found belatedly by
Clyde Tombaugh at Lowell Observatory in 1932 from plates exposed on
January 1931, as outlined by D. H. Levy et al. who noted the comet to be
diffuse with strong condensation with a tail at least 2' long in PA
about 270 deg on those 1931 plates.  Spacewatch astrometry of 2003
WZ_141 from 2003 Dec. 18 gave magnitude 17-18.

The following orbital elements by G. V. Williams (from 125 observations
spanning 1931 Jan. 12-2012 Dec. 13; mean residual 0".53), along with
residuals and an ephemeris, appear on MPEC 2012-X79.
