[On Nov. 13, at 4 p.m. ET, GOES-17 captured this GeoColor view of the Earth from its new orbital position over the Pacific Ocean.] [NOAA] On November 20, technicians observed an error from NOAA’s GOES-17 Advanced Baseline Imager (ABI) – unrelated to the ongoing issues with the loop heat pipe – that resulted in degraded infrared imagery. [GOES ABI install in Lockheed Martin clean room before launch. From NOAA] The technicians determined that a recent update to software that controls the ABI cryocooler system (which pumps heat away from the instrument’s detectors to cool them to their required operating temperatures) caused a memory error. Automated safety checks onboard detected the error and initiated shutdown of the cryocooler, according to procedure. The cryocooler operation is restored now, with no additional degraded imagery as a result of the error. In August, NOAA released GOES-17 Advanced Baseline Imager (ABI) “beta” level data and imagery—data which are still preliminary and not yet fully ready for use–to forecasters and scientific partners One Step Closer to Full Operations: GOES-17 “Beta” Data Set for Release Soon [This 16-panel image shows a snapshot of the continental U.S. and surrounding oceans from each of the Advanced Baseline Imager channels on July 29. This imagery was captured between the instrument’s “cool” and “warm” season, when all 16 channels are available 24 hours per day. During the instrument’s “warm” seasons, varied data outages are expected for 9 of the channels during nighttime hours. The ABI’s increased channels provide three times more spectral information than the previous GOES imager.
