Four range tests were performed with Santiago in December 2013 (12/2,
12/3, 12/6 and 12/18).  The last 3 tests had range data with a bias from
0 to 80m.  The Near Earth Network team is evaluating their configuration
to try to reduce the bias.  WS1 and Santiago will be performing range
tests with the spacecraft in-between DSN passes as their antennas are
available.  The ACE MOC will not be receiving telemetry during these
tests, but will look at recorded data for any issues.

WS1 performed range tests during these times in the past week.

With current solar activity and sunspot AR1944, NOAA Space Weather
Prediction Center (SWPC) received 2.5 hours of tracking from AFSCN
(006-2302z to 007-0155z) until the Korean Space Weather Center antenna
(KSWC) could resume tracking.  The last use of the AFSCN was on
11/13/2013 to test the new SCDs at VAFB.

========================================================================
Anomalies:

DSS-34 was unable to support the RNG ONLY track on 1/5/2014 due to
transmitter problems, DR#C109772.  There were 2 other southern
hemisphere ranging tracks (1/3 and 1/7) between the attitude maneuvers
on 12/31/2013 and 1/7/2014.
