  Status Change Summary

  GOES-11
  GOES-11 has returned to normal on-orbit mode from the Z-Axis Precession (ZAP) storage mode on June 3. GOES-11
  communications components will communications components will be used for the EMWIN testing, MSPS testing,
  and GOES-N communications equipment testing. The annual North/South inclination change maneuver is scheduled
  for June 22 and the return to storage mode will be activated on June 30.
