We have located the solar sources of 67 impulsive solar energetic particle (SEP) events, using type III bursts to narrow down the times of particle injection in the solar corona. This information serves as a direct means to test the model of the Sun-Earth magnetic field connection because the particles simply trace the field lines. We consider the standard technique to model the Sun-Earth magnetic field, known as the potential field source surface (PFSS) model for the coronal part and the Parker spiral for the interplanetary part. In each of selected SEP events, we calculate the distance of the footpoint of the well-connected field line from the observed source location. It is found that the technique does not work as well as when it is used to predict the solar wind speed and the polarity of the interplanetary magnetic field. We suggest what we need to do to better understand the Sun-Earth magnetic field connection, or, more broadly speaking, the interplanetary magnetic field, which is an important element in NASA's Exploration Initiative.
