OBSERVATIONS OF MINOR PLANETS
     The following precise positions of the Apollo objects 1972 XA
and 1971 UA have been obtained by M. Mattei and G. Schwartz with
the 155-cm reflector at Harvard College Observatory's Agassiz
Station.  Measurers: J. H. Bulger and C. Y. Shao.  The image of 1971
UA is trailed and the measurement uncertain.
