Goddard Space Flight Center was closed for the snow storm on 3/6/2013.
Automated operations continued without incident.

Work is continuing to have a range test with ACE and the SSC/Santiago
9-meter antenna.  The test will be used in planning for the DSCOVR
mission.  The ACE team has requested WS1 provide downlink only telemetry
so that we can monitor the ACE receivers during the test.
Interestingly, the Cortex equipment used by the NEN ground stations has
range tones at 81kHz and 83kHz.  These range tones can't be used when
ACE is at the high data-rate (87648bps).  Therefore the test will be
done with ACE at the medium data-rate (7968bps).
