Abstract: On September 23rd, 2012, the Geostationary Operational Environmental Satellite (GOES)-13, Imager was placed in standby in response to a spacecraft vibration anomaly that was ultimately determined to be caused by a malfunctioning filter wheel in the Sounder instrument. Several days prior to this event, GOES-13 Imager Channel 3 imagery exhibited oscillatory noise that was visually apparent. In response, a Fourier coherent noise analysis was performed using GOES-13 Imager space data. The analysis confirmed a noise frequency calculation by the National Oceanic and Atmospheric Administration (NOAA) Office of Satellite and Product Operations (OSPO) and showed that the GOES-13 Imager Channel 2 was also exhibiting oscillatory noise. Using historical data, the Fourier analysis also showed that the GOES-13 Imager coherent noise originated on July 13th, 2012, which was not visually discernible. To provide potential warnings of future anomalies, an operational system was implemented that provides GOES-EAST and GOES-WEST Imager coherent noise measurements that are updated daily on the GOES Imager Data Quality Monitoring website.
