Renewal: New Aspects of Acceleration and Transport of Solar Energetic Particles (SEPs) from the Sun to the Earth

: This report summarizes the research results of this task which were published in eleven refereed journal articles. The seven basic topics are: (1) Effects of coronal holes on properties of SEP events (Kahler et al., 2013, 2014); (2) Size distributions and scaling laws of solar flares and SEP events (Cliver et al., 2012; Kahler, 2013); (3) SEP event timescales and associated CME properties (Kahler, 2013); (4) Comparison of the intensities and energies of gradual SEP events with the dynamical properties of associated CMEs (Kahler and Vourlidas, 2013); (5) The roles of interacting CMEs and solar wind streams in SEP events (Kahler and Vourlidas, 2014a,b); (6) The cosmogenic nuclide event of 775 AD (Cliver et al., 2014) ; and (7) Abundance enhancements and CME associations of Fe-rich impulsive SEP events (et al., 2014a,b) .
