Topic: Correction - GOES-12 Anomaly Status Update
Message Issued: December 6, 2007, 1720 UTC
Satellites Impacted: GOES-12
Products Impacted: GOES-10 GVAR, LRIT, and DCS Rebroadcast
Date/Time of Initial Impact: December 6, 2007 1515 UTC
--------------------------
Details:
GOES-12 remains in power positive stationkeeping mode (thruster attitude
control) with all subsytems safe. The anomaly that caused the attitude
disturbances on GOES-12 has been identified by NESDIS engineers, and
NESDIS will attempt to return to normal on orbit mode at approximately
2300 UTC today. If successful, GOES-12 will be once again monitored
closely throughout the night and the day on Friday for any further
unusual disturbance torques. NESDIS will make a decision on the way
forward following an extended monitoring period which may last through
the weekend.
GOES-10 is operating as GOES-East with routine imager and sounder
schedules at: http://www.ssd.noaa.gov/PS/SATS/MESS/MSG3391948.01.txt
NESDIS is rebroadcasting GOES-10 GVAR (inclination correction on), LRIT,
and DCS now through GOES-12, starting at 1515 UTC today. Direct GVAR and
LRIT users should not need to repoint their antennas to GOES-10. Due to
interference, EMWIN is being transmitted solely through GOES-10.
If needed, NESDIS and NASA engineering teams are preparing procedures to bring
GOES-13 out of storage mode to on orbit mode.
(Corrected for GOES-13 preparations)
