COMET P/2013 CE_31 (MOSS)
S. Nakano, Sumoto, Japan, reports that he has identified observations of
P/2013 CE_31 (cf. CBET 3418) from Spacewatch astrometry (observer J. V. Scotti)
on 2000 Nov. 17 and NEAT/Palomar astrometry on 2002 Mar. 12. Nakano notes that
the Delta(T) corrections to his most recent orbit from the 2013 data alone were
-1.55 and -1.28 days, respectively, for the 2000 and 2002 observations.

After being notified by Nakano, additional NEAT/Palomar observations on four
nights spanning 2002 Feb. 4-Mar. 4, as well as NEAT/Haleakala data from 2002
Feb. 8 and Mar. 16, were found by M. Meyer (Limburg, Germany). The
following linked orbital elements by G. V. Williams, along with an updated
ephemeris, appear on MPEC 2013-E46.
