    * Daily solar flux is predicted to be around 113 over the next 3 days.
    
    * Daily earth geomagnetic activity is predicted to range from quiet to active levels with the possibility for isolated
    minor active periods at high latitudes over the next 3 days.
    
    * ISS is currently in LVLH attitude mode.
    
    * The ISS is currently scheduled to perform another orbit-adjust / phasing burn later this week. The approximate UTC
    time is 239:00:32:17 ; maneuver delta-V is 2.42 meters/second.

         The following on-orbit vector is provided by NASA
         Johnson Space Center Flight Design and Dynamics
         Division for use in ground track plotting programs.
         It should not be used for precise applications
         or analysis!
