Data Capture:  100%  DOY 031-038 2010


The start of operational testing in the MMOC has been DELAYED 1 week and
is now scheduled for Tuesday 02/23/2010 (DOY 054).  All passes starting
with DOY 054 will be taken from the MMOC.  If there are significant
problems, operations would switch back to the old MOC and DSN will be
able to reload the configuration tables for the next day's pass.  The
Operations Readiness Review (ORR) is scheduled for 03/31/2010.

Anomalies:

DOY 036  02/05/2010  S-ACE-0482  G10-0005  AC3PR3 Printer Failure
The printer used for trending was unable to print.  Hardware Maintenance
was notified and fixed the printer.
IMPACT:  Minimal.

DOY 039  02/08/2010  S-ACE-0483  G10-0004  C&C Reboot
Data capture statistics was being processed on ac1ws3.  The weekly
archive had not been purged in the previous week and the data capture
statistics caused ac1ws3 to be out of memory.  The automation software
(C&C) was automatically rebooted and was running within 10 minutes.
IMPACT:  Minimal.  No commanding was required during the 10 minute
reboot.
