OCRs:

Update: MOCR ACE-366 Relax HGA constraint from 9 to 11 degrees for 2016 Summer Campaign
- The 2016 Extended HGA Summer Campaign concluded with the 09/06/2016 attitude maneuver.  The 2016 campaign began on 06/07/2016.
- OSIRIS-REx (ORX) was scheduled to launch 09/08/2016.  Several ACE DSN supports were impacted by the proposed launch contingencies.  The return to the 9 degree upper limit antenna constraint allowed ACE to resume operations with WS1.
- WS1 supports scheduled for 9/14/2016, 9/15/2016 and 9/19/2016.
