Solar Flux EUV

Extreme Ultraviolet (EUV) radiation has major impacts on the ionosphere.  An excess can result in radio blackouts of terrestrial High Frequency (HF) communications.  EUV Flares also reduce the lifetime of Low Earth Orbiting (LEO) satellites by causing increased atmospheric drag.  They do this by depositing large amounts of energy in earth’s upper atmosphere (thermosphere), causing it to expand into these satellites’ orbits.  This EUV product will provide improved coverage of these important wavelengths and information that will aid in preserving ground-based radio communications and navigation systems, as well as satellite orbit.
