[Skywarn] Solar rfi

[Lloyd Colston]

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.
