201202Aurora.jpg Auroral breakup (substorm) and associated phenomena. In particular, :
  • - Auroral images from satellites and ground
  • - Plasmoids in the magnetotail
  • - Causality between auroral breakups and magnetotail reconnection
  • - Plasmoids in the magnetotail
  • - Ionospheric conductance created by the Solar EUV and auroral particles
  • CV
