Observations of non-conjugate theta aurora
Abstract
Based on simultaneous imaging data from IMAGE FUV and Polar VIS Earth camera and DMSP particle measurements we report two events where a theta aurora was observed in one hemisphere but not in the other. IMF control and hemispherical conductivity differences are suggested as possible explanations for the occurrence of non-conjugate theta aurora.
