         The orbital elements above for 2002 SY50 bear a striking resemblance to
    those of 1937 UB (cf. MPC 3014).  However, attempts by the undersigned and
    others to link definitively the two objects have so far failed.  Good coverage
    (including radar observations) at this opposition and recovery in early 2003
    should allow this suggested linkage to be confirmed or denied.  It should be
    noted that both the 1937 and the 2002 observations yield orbits that allow
    very close approaches to the earth, Venus and Mars, and this chaosticity,
    coupled with the low-quality astrometry in 1937, make verification of the
    linkage very difficult at this time.
