We received the following information from our Mission Operations Division concerning the potential for outages of the GOES data stream including GVAR (GOES VARiable) Imager and Sounder, EMWIN (Emergency Managers Weather Information Network), SAR (Search and Rescue), Low Rate Information Transmission (LRIT), GOES Data Collection System (DCS), Sensor Data (SD), Telemetry and Command (T&C), Weather Facsimile (WEFAX), Data Collection Platform Report (DCPR), Multi-use data link (MDL), etc. The Wallops and Fairbanks Command and Data Acquisition Stations (CDAs) and Environmental Satellite Processing Center (ESPC) receiving antennas may experience periods of Solar RFI as predicted below. Solar RFI can cause loss of telemetry lock and command capability, as well as degradation or loss in the GVAR data.
