2) Status of ACA workstation "coot":  coot had apparently been rebooted for
   installation of the new disk.  I restarted TLM_REC, TLM_MON, ACA_MON and
   the basic suite of disp/rtplot displays.  All looks well, and telemetry
   file is growing in the tlm/raw directory.

3) Radiation environment:  Radiation evironment is still moderate, but
   generally is declining.  EPHIN rates E1300 and P4GM are about 1/5 of the
   RADMON triggers (see rates in note 1), but the flux is headed downward,
   and we are approaching the perigee pass safing at about 333:2012.  The
   Costello index is fairly high, hovering around 4.
