Geostationary Operational Environmental Satellites—R Series

A collaborative NOAA & NASA program

Data Products: MAGNETOSPHERIC ELECTRONS and PROTONS: MED and HIGH ENERGY

GOES-17 SEISS Magnetospheric Electrons and Protons: Medium and High Energy data May 4-7, 2018, showing the complex response of radiation belt electrons and protons associated with a geomagnetic storm. The large increase in the levels of electrons triggered a radiation belt alert by SWPC.

The GOES-R Space Environment In-Situ Suite (SEISS) includes magnetic energetic ion sensors for both low and high energy levels. One of the space weather alerts issued by NOAA’s Space Weather Prediction Center (SWPC) will depend upon this product in the GOES-R Series era. These electrons are very penetrating, and can cause electrical breakdown and discharges of materials deep inside of equipment (deep dielectric charging). They can also adversely affect high frequency radio transmissions and therefore GPS navigation.
