  5. Kristian Birkeland (1867-1917) • The ”first auroral physicist” • Professor at 31 years old • Experiment + Theory = Innovation (60 patents) • Fixation of Nitrogen – gave birth to Norsk Hydro/Yara - a world leading fertilizer company • After three expeditions in 1902- 1903 he concluded that northern lights are associated with currents floating along magnetic field lines – The Birkeland currents 8/23/2016 5

  32. Halloween storm, October 2003 • Aircrafts communication systems at HF/VHF suffered severe degradation and periods (over 130 hours) of blackout • Trans-polar flights were re-routed to avoid radiation hazards • More than 20 satellites were affected; one Japanese satellite lost • Astronauts on ISS had to move into service module for radiation protection • FAA issued first-ever alert on radiation doses received by airplane passengers above 25,000 ft • Power system failure in Malmo, Sweden (30 October) • US Coast Guard to temporarily shut down LORAN C navigation system • WAAS service interrupted over US; high-latitude GPS receiver outages 8/23/2016 32

  38. Space weather • Ionospheric irregularities produce fluctuations in radio waves, called Signal emitted by satellite scintillations • Severe amplitude fading and strong phase scintillation affect the reliability of GPS systems and satellite communications. Scintillations at the receiver The scintillations occur mainly at polar, auroral and equatorial regions; more frequently around the solar maxima 8/23/2016 38
