Study of the Origins and Interplanetary Propagation of Geoeffective Disturbances.
Abstract
This contract has provided a program. of research whose overall goal has been a better understanding of the origins and interplanetary propagation of geomagnetic disturbances and also the dynamics of Solar Energetic Particle events (SEPs). The research built on addressing several areas: the solar eruptive phenomena which lead to sporadic geomagnetic storms; analyses of SEPs to identify particle injection profiles at the Sun; the role of Coronal Mass Ejections (CMEs) in the production of SEPs and shocks at 1 AU; view of the heliospheric current sheet and coronal streamer belt; identification of CMEs in the interplanetary medium, and establishment of their heliospheric characteristics; magnetic clouds as interplanetary signatures of CMEs; solar flare/CME relationships; e-folding decay time of intense soft x-ray burts as a forecaster of significant proton events at 1 AU; CMEs as a tracking mechanism for the solar activity cycle; systematic search for candidate disconnection structures in the wake of CMEs; and the development of a Ground Level Event (GLE) database with access by GLEINFO; Shuttle Potential and Return Electron Experiment (SPREE) measurements and analysis.
