     The Minor Planet Electronic Circulars contain information on unusual
         minor planets and routine data on comets.  They are published
   on behalf of Commission 20 of the International Astronomical Union by the
          Minor Planet Center, Smithsonian Astrophysical Observatory,
                          Cambridge, MA 02138, U.S.A.

     A posting on the Minor Planet Mailing List by Denis Denisenko suggested
that the object designated 2007 VN84 on MPEC 2007-V69 might be the Rosetta
spacecraft.  Our investigation of this possibility, using information from
the Satellite Situation Center (http://sscweb.gsfc.nasa.gov/), show that
this suggestion is indeed correct.  The positional information available on
the SSC website does not begin until Nov. 12.0 UT.  However, the agreement
at this time between the predicted positions for Rosetta and 2007 VN84 is
well within 1'.  The minor planet 2007 VN84 does not exist and the designation
is to be retired.

      This incident, along with previous NEOCP postings of the WMAP spacecraft,
highlights the deplorable state of availability of positional information on
distant artificial objects (whether in earth orbit or in solar orbit).  The
Distant Artificial Satellites Observations (DASO) page on the MPC website
(http://www.cfa.harvard.edu/iau/SpaceJunk/SpaceJunk.html) lists a number of
such objects, but has to be updated on a fairly regular basis from five
different sources and data is not always available for the timespans needed.
A single source for information on all distant artificial objects would be
very desirable.
