    3. Satellites useful for simultaneous observation programs with small
cameras; and for gravitational and atmospheric studies.  (* indicates updated
information since the last issue.  The magnitude is an approximation; it assumes
75% illumination of the satellite and 900 km range.  SPACEWARN would appreciate
suggestions to update this list.)

DUE TO BUDGETARY CONSTRAINTS, THIS CATEGORY HAS NOT BEEN LISTED.

    4. Satellite objects that are nearing their decay into the atmosphere.
(Orbital observations of these objects during the decaying phase are useful for
atmospheric studies.  Note: For maneuverable spacecraft the prediction may be
invalid.)

DUE TO BUDGETARY CONSTRAINTS, THIS CATEGORY HAS NOT BEEN LISTED.
