Two samples of trajectories of 30–40 nm dust with β = 0.163, projected onto the heliocentric distance-heliographic latitude plane (the r,λ plane). The magnetic field is positive in the northern hemisphere and negative in the southern hemisphere (defocusing configuration). The crosses mark the daily positions of the spacecraft during the second orbit. The diamonds show the upper and lower limits in latitude for each of the two samples. The initial latitudes are between −12° and 12° (Czechowski & Mann 2012). Only a small fraction of trajectories encounter the orbit of the spacecraft.
