This cartoon's paper documents a very nice correlation between the arrival
time of solar energetic particles (SEPs) and the heliographic distance
of the source flare and the spacecraft's magnetic footprint on the
photosphere.
This makes use of the two STEREO spacecraft and the data from ACE, nearer
to the Earth.
One possible explanation is as shown, namely that the wave itself, in the
chromosphere or low corona, dictates the particle injection.
Other plausible explanations
might be possible.
