Ongoing Activities:

Attitude Training - The FOT continues training on attitude determination,
maneuver planning, and maneuver execution.  The transition date is
tentatively scheduled for 07/01/06.

RIONET - A licensing issue with the firewalls needs to be resolved before
the MOC can be transitioned.  

Space Link Extension (SLE) - ACE SLE version 2.1 was delivered to the
Library on April 28, 2006.  The delivery to the ACE MOC will not occur until
after String 3 is converted to the RIONET.

============================================================================
Extra Activities:

Due to the maneuver on Monday 06/26/06, there was not enough time to perform
the weekly SWEPAM calibrations.  The calibrations were completed on Tuesday
instead.

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

DOY 177 (06/26/06)  G06-0067 - String 1 Tape Drive 
The tape drive on string 1 has been taking twice as long to read the tapes
for the last few weeks.  The Sys Admin's replaced the tape drive on
Wednesday 06/28/06.  
IMPACT:  Weekly archiving completed, but took longer than expected.

DOY 178 (06/27/06)  G06-0068 - Telemetry Outages
Due to network problems, there were 3 brief telemetry outages from 17:42 to
17:55.  DR N103760.
IMPACT: All data was recoverable from the recorders.  

DOY 180 (06/29/06)  G06-0069 - AC1XT1 Malfunction
After the tape drive replacement, the Sys Admin's could not log in to
AC1XT1.  Currently there is no replacement for the xterm.
IMPACT: None.  The FOT does not use AC1XT1 for operations.
