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

                               DELETION OF 2020 SO                           
         The designation 2020 SO, announced on MPEC 2020-S78 and published in MPS
    1245724, is being deleted. Based on its orbital evolution Paul Chodas suggested
    that 2020 SO could be the Centaur upper stage for the Surveyor 2 mission 
    (1966-84B), launched on September 20, 1966. Subsequent observations revealed a
    large area to mass ratio of the object supporting the artificial nature of the
    object. The object was temporarily captured on geocentric orbit and will leave
    the Earths Hill sphere in March 2021.
