Activities:

Data Capture:  100%  DOY 085-092 2012

WS1 continues to work on their ranging configuration/equipment for ACE.
WS1 is also working on automatically detecting the data rate
(low-rate/high-rate) the spacecraft is transmitting.  WS1 will schedule
more ACE tests when changes have been incorporated into their system.

Anomalies:

DOY 089 03/29/2012  S-ACE-0639  S12-0001  SWEPAM-E Overcount Alarm
The SWEPAM-Electron Overcount Alarm flagged on Thursday 03/29/2012 and
intermittently through the rest of the week.  The Overcount threshold
had been lowered on 10/07/2005 for the solar minimum (6.5 years ago).
The instrument team will look at the data to determine the next course
of action.
IMPACT:  The instrument automatically reduces voltages when the
overcount alarm occurs.
