New data from NOAA GOES-16's Space Environment In-Situ Suite (SEISS) instrument
10 February 2017
The new Space Environment In-Situ Suite (SEISS) instrument onboard NOAA's GOES-16 is working and successfully sending data back to Earth.
A plot from SEISS data showed how fluxes of charged particles increased over a few minutes around the satellite on 19 January 2017. These particles are often associated with brilliant displays of aurora borealis at northern latitudes and australis at southern latitudes; however, they can pose a radiation hazard to astronauts and other satellites, and threaten radio communications.
Information from SEISS will help NOAA's Space Weather Prediction Center provide early warning of these high flux events, so astronauts, satellite operators and others can take action to protect lives and equipment.
