Abstract

The conclusions reached by the Particle Acceleration Team are summarized. The first is that a number of protons and very-high-energy electrons are accelerated during the impulsive phase, with the acceleration exhibiting a very pronounced time structure. Evidence is seen as mounting for a rather continuous and long-lasting acceleration (gradual phase) following the impulsive one, although it is not related in particular to proton acceleration. The second conclusion is that certain flares have something to do with emerging (or evolving) flux, that is, interacting loops in general. Recent indications of reconnection phenomena are noted. The third conclusion is that interplanetary high-energy particle events are only weakly related, if at all, to the signatures of acceleration events occurring in the immediate vicinity of the flare site. Attention is confined to the highest energy particle acceleration, which, it is noted, would previously have been referred to as the second phase.
