The Space Environment Center (SEC) Space Weather for Aviation Service Providers web site is designed for the aviation community to communicate space weather information in terms that are easy to interpret and understand. Solar events can have a detrimental impact on airlines and ground equipment. Space weather storms can result in lost or degraded communications, unreliable navigational equipment, flight-critical electronic system problems, and radiation hazards to crew and passengers.
Displays show the most recent data available at SEC. See the sample web page which shows how the page looked during the high solar activity in September 2005. See Data and Products for earlier data.
