Subject: GI: Correction - GOES-12 Anomaly Status Update 12/4/07 - Issued 12/6/07 From: Brian Hughes <Brian.Hughes@xxxxxxxx> Date: Thu, 06 Dec 2007 12:19:26 -0500 To: Brian Hughes <Brian.Hughes@xxxxxxxx> 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.
