Subject: Administrative: Update #1: GOES-13/14/15 Fall 2015 Solar Update #1: GOES-15 (GOES-West) Solar RFI predicted times have been modified. Topic: GOES-13/14/15 Fall 2015 Solar RFI predicted times are now available Date/Time Issued: September 30, 2015 1800 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: October 5, 2015 1640 UTC Date/Time of Expected End: October 19, 2015 2149 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.
