Stereo Impact Investigation Early Mission Observations of The Solar Wind Structure, Its Sources and Its Interplanetary Consequences
Abstract
STEREO carries two main in-situ investigations to measure the solar wind plasma and interplanetary energetic particles and magnetic fields at 1 AU at the increasingly separated STEREO sites. These measurements have provided the opportunity to study the connections between the quiet corona and the solar wind structure during the first months of the mission's operation. In addition to the possibility of observing the same features at multiple sites, in combination with the SECCHI imaging investigation and SOHO and ACE the data allow us to explore specific questions regarding solar wind source regions and stream structure geometry. For example, not all high speed-low speed stream interaction regions have similar character; some exhibit more substructure and some have stronger locally accelerated particle signatures than others. We investigate this and other features taking into account the coronal source differences.
