Update #1: This is a reminder that GOES-15 supplemental operations will end on March 2, 2020 at 1600 UTC. Due to operational impacts from the GOES-17 Advanced Baseline Imager (ABI) performance shortfall, NESDIS will return the GOES-15 imager to temporary service during the peak period for Eastern Pacific tropical cyclones, around August 2020. NESDIS and NWS will work to define the specific operational period required.M-B

GOES-15 supplemental operations to GOES-17 will be extended to March 2, 2020.M-B After that date, the GOES-15 spacecraft will be placed in standby. GOES-17 will continue operating in the GOES-West role at 137.2 degrees west with all instruments operating nominally. Due to operational impacts from the GOES-17 Advanced Baseline Imager (ABI) performance shortfall, NESDIS will return the GOES-15 imager to temporary service during the peak period for Eastern Pacific tropical cyclones, around August 2020. NESDIS and NWS will work to define the specific operational period required. After August 2020, GOES-15 will be returned to on-orbit storage.

Additionally, to facilitate user awareness and effectively prepare for the transition from GOES-15 to GOES-17 GOES-West operations, the Office of Satellite and Product Operations (OSPO) has established the following informational webpage on the transition: (http://www.ospo.noaa.gov/Operations/GOES/16/transition.html). Users may reference this webpage and refer to ESPC notifications for the latest updates on the transition.M-B
