Data Capture:  100%  DOY 337-342 2013

A second DSS-15 demo had been scheduled for Wednesday 12/4/2013 (DOY
338) to acquire extra antenna time.  DSN cancelled the demo due to servo
maintenance.  Fortunately, LADEE had reduced their DSN usage on
12/4/2013 and ACE was able to fit in 2 short passes.

Santiago "range-only" certification tests began on Monday 12/2/2013.
The first set of tests will be with Santiago's 9m antenna.  The first
test (12/2) had valid doppler data, but the range data off by 17,000km.
The second test (12/3) had valid doppler and range data.  The third test
(12/6) appeared to have valid data, but is awaiting official word from
FDF.  A fourth test with Santiago's 9m antenna has been scheduled for
12/18/2013 in order to have 3 successful tests for the Near Earth
Network's certification process.  Tests of Santiago's 13m antenna will
be performed in January 2014.

Anomalies:

DOY 344  12/10/2013  S-ACE-0670  G13-0013  JPL Network Problems
A problem with the JPL RPG firewall caused the MMOC to lose the network
connection to JPL and DSS-27 for 21 minutes (1756-1817z).  DR#N109241
IMPACT:  Recorded science data was recovered after the network was
restored.  No real-time data to NOAA Space Weather Prediction Center for
21 minutes.
