The above ephemeris is back-dated in the hope that images might have
been recorded near 1994 TB.
With reference to 1997 RT5 (MPEC 1997-R12), C. Veillet notes that the
predicted position in late June was some 30 arcsec off the edge of the
CFHT frames on which 1996 RR20 was recovered (MPEC 1997-N01).
