Topic: GOES-13/14/15 Spring 2017 Solar RFI predicted times are now
available

Date/Time Issued: February 23, 2017 1445 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, 2017 1704 UTC

Date/Time of Expected End: March 9, 2017 2144 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.

Solar RFI predicted times for the Fall 2017:
