Dear Colleagues,

The H-Maser clock input to the receiver at the Goddard Space Flight 
Center in Greenbelt, MD (GODE), had two interruptions in the past few 
days. The first, one minute, outage was not planned, the second outage 
was a scheduled maintenance of the H-Maser. During the outages the 
Ashtech CGRS receiver was not switched to internal clock steering, and 
the H-Maser lost phase lock and the LO was drifting.  The two outage 
periods were as follows:

February 4th (2008.035)  14:07 UTC - 14:08 UTC
February 6th (2008.037)  16:30 UTC - 22:15 UTC

An updated log reflecting the outages has been submitted to the IGS-CB.

We would also like to acknowledge our contact personnel at the Goddard 
Space Flight Center in managing the outage and restoring operations quickly.

Maintenance and operations of the GODE station is a collaborative effort 
supported by JPL, UNAVCO, and the NASA Goddard Space Flight Center with 
funding provided by NASA's Earth Surface and Interior Focus Area - 
Science Mission Directorate.

Best regards,

-Oivind Ruud
