COMMENTS:
COMMENTS: Because no BAT_Position Notice was received, this FOM Notice was forced out after watchdog expiration.
COMMENTS: This was of sufficient merit to become the new Automated Target;
COMMENTS: but if the Current PPT has a greater merit, then we will not request a slew.
COMMENTS: FOM will request the s/c to slew.
COMMENTS: The S/C has yet to make its decision about safe to slew or not.
COMMENTS: This does not match any source in the ground catalog.
COMMENTS:
COMMENTS: The next comments were copied from the BAT_POS Notice:
