Application to an
interplanetary shock:
What if e, r vary with time?
What if e, r vary with time?
lPhysical characteristics of a shock change greatly as it moves out from the Sun
lObservations: high energy particles are accelerated only when shock is near the Sun
lNear Sun: tacc (=1/r) was low, t /tacc was high, spectrum does not roll over until high energy (rollover mechanism not clear)

lInterplanetary space: tacc greatly
increased
lEffectively decouple SEP, ESP acceleration
