Solar Flare and Interplanetary Particle Acceleration and Coordination of Ground-Based Solar Observations in Support of U.S./International Space Missions

The four components of this project span particle acceleration in solar flares as well as the coordination and development of solar ground-based solar observations. The PI plans to (1) expand previous analyses showing a direct relationship between specific hard x-ray spectral evolution signatures in flares and high-energy interplanetary proton events; (2) examine properties of the 450 unsampled flares to test a proton prediction algorithm previously derived; (3) explore high energy spatial characteristics of these events to gain insight into source geometries; (4) address data collected during the maximum of cycle 22; and (5) employ an REU assistant in analyzing data for rapid optical fluctuations and linear polarization signatures. In addition, this project will coordinate ground-based observations in conjunction with new space missions. Finally, the PI plans to support, in part, numerous observing campaigns.***
