Activities:

Data Capture:  100%  DOY 345-352 2011

The ACE passes in the upcoming week (12/20/2011 through 12/29/2011)
average 2.6 hours per day.  The GRAIL mission is performing their Lunar
Orbit Insertion and their antenna view time is the same as ACE's.  ACE
is allocated 3.5 hours per day but can squeak by with 2.75 hours per
day.  The SSR playback will fall behind by ~10 hours over this period,
but no data loss is expected.  Data capture should be caught up during
the long pass scheduled for 12/30/2011.
