Details/Specifics of Change:

On January 4, 2023 at 1800 UTC, the GOES-18 satellite will be declared the Operational GOES-West satellite. Until that transition date and during this final period of Post Launch Product Testing (PLPT), GOES-18 products are considered non-operational regardless of their validation maturity level. All products and services (e.g., GRB, AWIPS, PDA, CLASS, NODD) containing GOES-17 data will be transitioned to GOES-18 data. GOES-18 will continue to operate out of its current location of 137.0 degrees west through the transition.

Following the transition of GOES-18 to GOES-West, GOES-17 will commence drifting to the storage location at 105.0 degrees west.
