GOES-16 Drift and Transition to Operations
January 31, 2018
GOES-16 began drifting to the GOES East operational location of 75.2 degrees west longitude on November 30, 2017. GOES-16 reached 75.2 degrees west on December 11, 2017 and data flow resumed to users on December 14. On December 18, 2017, GOES-16 was declared NOAA’s GOES East operational satellite.

On December 14, 2017, GOES-13 direct GVAR was disabled. GOES-13 GVAR and LRIT were relayed through GOES-14 until January 8, 2018, at which time the GOES-13 GVAR relay through GOES-14 GVAR was disabled. GOES-13 ceased transmitting data on January 8 and began drifting to its storage location at 60 degrees west on January 9. The satellite arrived at 60 degrees west on January 31.
Now that the GOES-13 GVAR data stream is permanently deactivated, a number of satellite derived products using GOES-13 data are unavailable. NOAA/NESDIS plans to produce a set of equivalent products from the new GOES East satellite (GOES-16); however, in some cases legacy products will be degraded or discontinued entirely as a result of the loss of GOES East coverage.

Notes: No planned maneuvers / special operations during Thanksgiving and Christmas holidays. No GOES East transition / interruption during Critical Weather Days.
GOES East assignment details which do not appear above:
- LZSS data availability and SUVI cal activities are not on this slide because they are not pertinent to the user community.
- ANCF/BNCF AWIPS and PDA distribution activities are not on this slide because those notifications are handled separately via NWS and PDA, respectively.
