OCRs:

6/07/2016 MOCR ACE-366 Relax HGA constraint from 9 to 11 degrees for the 2016 Summer Campaign
The 2016 Extended HGA Campaign was discussed & approved at the recent ACE Science Working Team (SWT) 
meeting held on 5/23-24/2016.  This will be the third consecutive year for this summer campaign. The 
HGA constraint change will effectively allow slightly higher sun angles, which in turn will improve 
the SWEPAM-I density measurement.  The FOT began using the 11 degree constraint with the attitude 
maneuver on 6/07/2016.  The campaign is tentatively scheduled to conclude September 2016.
