Subject: GOES-13/14/15/16 Fall 2018 Solar RFI

NESDIS has provided the following information concerning the potential for outages of the GOES data stream, including EMWIN.

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. 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.
