Subject: Administrative, GOES Spring 2014 Solar RFI predicted times --047d7ba983ce9e2b8104f2d842bc Content-Type: text/plain; charset=ISO-8859-1 Topic: GOES-13/14/15 Spring 2014 Solar RFI predicted times are now available Date/Time Issued: February 20, 2014 1535 UTC Product(s) or Data Impacted: GOES-13/14/15 Imager and Sounder Data plus Ancillary Services (GVAR, SAR, LRIT, EMWIN, DCS, etc.) Date/Time of Initial Impact: February 23, 2014 2105 UTC Date/Time of Expected End: March 9, 2014 2143 UTC Length of Outage: See table in details. Details/Specifics of Change: The potential for solar radio frequency interference (RFI) with a satellite downlink circuit will occur whenever the Sun passes into the beam of the ground station receiving antenna. 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.
