NESDIS Office of Satellite Operations (OSO) and Office of Satellite Data Processing and Distribution (OSDPD) have monitored GOES-12 overnight, with Image and Navigation Registration (INR) recovery successful. GOES-12 will be placed back as operational GOES-East at 1500 UTC.

At 1500 UTC, all products including but not limited to GINI (AWIPS), ESPC Remappers, GOES Derived products, Radiances, Satellite Cloud Products (SCP), LRIT will switch back to GOES-12. ESPC personnel will closely monitor data and products during the changeover.

Users receiving GVAR directly from GOES-12 should be receiving GOES-12 imager and sounder data. GOES-12 is currently running the INR recovery schedule (19-minute Full Disk scans at XX:15 and XX:45 UTC with CONUS soundings at XX:46). OSDPD and OSO will coordinate on when GOES-12 will be placed back into routine mode.

Users obtaining GOES-13 GVAR directly from GOES-13 are recommended to switch back to GOES-12. GOES-13 will remain in a GOES-East scanning schedule until OSO and OSDPD determine that GOES-12 is stable for operational GOES-East activity.

GOES-13 is located at 105 degrees West and has WMO Satellite ID #257
GOES-12 is located at 75 degrees West and has WMO Satellite ID #256

UPDATE #12 1/5/2009 @ 1230 UTC

GOES-12 has undergone a successful anti-ice decontamination of the imager, and is slated to return to imaging and sounding on Monday, January 5, 2009 at 1500 UTC. At this time, GOES-12 will be placed on an Image and Navigation Recovery (INR) schedule (19 minute Full Disk scans at XX:15 and XX:45, CONUS Soundings at XX:46). The length of the INR recovery schedule will depend on the successful INR recovery of GOES-12. GOES-13 will be maintained as GOES-East through the GOES-12 INR recovery period.

For users pointing directly to GOES-12 and obtaining GOES-13 GVAR: At 1500 UTC on 1/5/09, GOES-12 GVAR will commence directly from GOES-12, but image navigation and registration may be out of desired specifications for a period of time. Users may want to consider adjusting their antennae to obtain GVAR directly from GOES-13.

** ESPC will continue to produce operational GOES-East product from GOES-13 (Remapper, GINI/AWIPS, radiances, derived products, interpretive products) during the GOES-12 INR recovery. ESPC will monitor GOES-12 data, and if INR recovery is successful, switch GOES-East operations back to GOES-12 on or about Tuesday, January 6 at 1500 UTC. **

GOES-12 will be maintained at Midnight Black Body Calibration Correction (MBCC) Mode 1 (instant averaging) until Thursday, January 8th when SOCC will switch calibration mode back to MBCC Mode 3 (4 day averaging). SOCC reports a 10-20 percent signal gain on GOES-12 following the successful decontamination.

Background Notes:
GOES-13 is located at 105 degrees West and has WMO Satellite ID #257

Satellite imagery is being produced for AWIPS and SATEPSDIST users from GOES-13.
GOES derived products (winds, soundings) from NESDIS are being produced from GOES-13.

For ground ingest software, you may need to contact your ingest hardware/software provider for any relevant updates to your system in order to ingest GOES-13 data.

To account for some noted striping in imager and sounder data from GOES-13, the SOCC implemented SPS Calibration Bias Mode (from 2 instead of 1) and MBCC (Midnight Blackbody Calibration Correction) at 1900 UTC on Wednesday December 17.

Data Affected by the Outage: All products from GOES-12
Date and Time of the Outage: 12/14/08, 2218 UTC , 5:18 pm EST
Length of the Outage: Unknown

Status of the GOES-12 Anomaly:
For the thruster problems on GOES-12, there has been NO leak seen today. SOCC (Satellite Operations Control Center) engineers will monitor GOES-12 for a few days for further analysis, prior to any decision for an attempt to return GOES-12 to GOES-East primary operations. There are no current plans to move GOES-13 from its current location at 105 West.

In the meantime, we will be running in the current configuration until further notice. GOES-13 GVAR data will continue to be sent out to users via both GOES-12 and GOES-13. Broadcast services of LRIT, EMWIN, and DCS are being routed through GOES-12. GOES-East direct broadcast users may want to adjust their antennas to obtain data directly from GOES-13.

To account for some noted striping in imager and sounder data from GOES-13, the SOCC implemented SPS Calibration Bias Mode (from 2 instead of 1) and MBCC (Midnight Blackbody Calibration Correction) at 1900 UTC today.

Notes:
There will be a GOES-13 East/West maneuver tomorrow, Thursday December 18 in order to keep GOES-13 on station. Data will be out from 2258Z-2314Z.

Message Issued: December 1, 2008, 1400 UTC
Satellites Impacted: Meteosat-9 and Meteosat-8
Products Impacted: All Meteosat-9 data and products from NOAA, including the Meteosat-9 DOMSAT Service
Date/Time of Initial Impact: December 1, 2008 1200 UTC
Details: NOAA has received the following bulletin from EUMETSAT:
Meteosat Prime Service During Meteosat-9 Spacecraft Decontamination As part of routine spacecraft operations, a Meteosat-9 spacecraft decontamination will be performed between 1 - 9 December 2008. During this period the Meteosat-9 SEVIRI Image and Meteorological Product services will be unavailable and will be replaced by the equivalent services from Meteosat-8. Meteosat-8 data will be rectified to 0 degrees during the decontamination period. The period of Meteosat-8 data to take the place of Meteosat-9 is scheduled from December 1, 2008 at 1200 UTC to December 9, 2008 at 1200 UTC.

NOAA retransmission of encrypted Meteosat data, uplinked from the Wallops Command and Data Acquisition Station, should not be affected. For users accessing Meteosat data via DOMSAT, NOAA will forward the Meteosat-8 encryption keys prior to the start of the planned Meteosat-8 swap (December 1, 2008 at 1200 UTC)

Meteosat-8 data will be rectified to 0 degrees during the decontamination period.

UPDATE: 12/15/2008, 0845 UTC, 03:45 AM, EST
UPDATE: GOES-13 will be switched to GOES-East beginning at 0500 UTC (12:00 p.m. EST).
Details of the Outage: At around 2200 UTC, GOES-12 s uffered a thruster anomaly causing the suspension of GOES-12 imaging and sounding schedules. At 2303 UTC, GOES-11 (GOES-West) was placed into Full Disk mode to cover for the GOES-12 outage. At that time, the GOES ingest a nd NOAAPORT Interface (GINI) was switched to alternate mode to allow delivery of GOES-11 data to East users.

At around 0500 UTC, once ingest of GOES-13 data is verified by ESPC, the GINI and all GOES-East products will be fed with GOES-13 imager and sounder data.

ALL Services (LRIT, EMWIN, DCS, SARSAT) will remain on GOES-12, and GOES-13 GVAR will be retransmitted through GOES-12. Users currently receiving services including GVAR from GOES-12 should not need to repoint to GOES-13.

It is anticipated that this configuration will remain in place for at least 24 hours. Data Affected by the Outage: All products from GOES-12
Date and Time of the Outage: 2218 UTC , 5:18 pm
EST Length of the Outage: Unknown
