a part of bulletin:

Date/Time of Initial Impact: October 18, 2012 at 1444 UTC - Switch to GOES-13 initiated.

Date/Time of Expected End: October 18, 2012 at 1445 UTC - Switch to GOES-13 completed.
    Note:  GOES-14 Drift Stop Maneuver will be executed October 19, 2012 at 1356 UTC


Details/Specifics of Change:

Tests of GOES-13 instrumentation have demonstrated the Imager and Sounder are ready to return to GOES-East operational service.  The root cause of the GOES-13 anomaly was a motor vibration in the sounder filter wheel subsystem that was transmitted on to the imager and sounder optical bench.  Mitigating steps have been taken to suppress the vibration and in addition, outgassing of the sounder has improved the sounder detector performance.  The noise in the Sounder shortwave data has been reduced compared to pre-anomaly levels.  The return of GOES-13 to operational service also optimizes the long term continuity of the GOES constellation.

Products requiring a climatology of 30 days will not be generated until the requisite number of fixed satellite location days have passed:
- ASDTA SMOKE (Automated Smoke Detection and Tracking Algorithm)
- GASP (GOES Aerosol and Smoke Product)
- GEO-SST (No NETCDF format)
- GSIP-FD (GOES Surface Insolation Product-Full Disk)

RSO and SRSO schedules from GOES-13 will be available to the NWS immediately after the switch is completed.  A final stop maneuver of GOES-14 will occur on October 19, 2012 at 1356 UTC placing it at a position of 89.5 degrees West longitude where it will remain in standby until
further notice.
