Statistical Relationships in Characteristics of a Sample of Interplanetary Coronal Mass Ejections Detected Near Earth
Abstract
Using in situ measurements of solar wind conditions near Earth, we compared the signatures of a sample of transients, which we tentatively identify as magnetic clouds. Images from several solar observatories were utilized to identify the source eruptions which launched each ICME from the Sun. The plasma conditions within these structures were compared, and trends were sought that would correlate with the type of solar progenitor structure that spawned the eruptions. Additionally, a magnetic model was fitted to the measurements of each ICME detected near Earth. We present findings that suggest a systematic difference in cloud structure, depending on progenitor type; also, we present results indicating a relationship between the speed of transit from Sun to Earth and the magnetic field strength in the ICME.
