The ISEE-2 spectrometer used in detection of electrons with energy greater than 20 keV, and protons of more than 25 keV has measured similar pitch angle distributions and intensities, during a single pass through the magnetopause, in the cases of (1) flux transfer events in the magnetosheath and (2) events, previously designated inclusion events, in the magnetosphere. Evidence is inferred from this for the position that magnetospheric magnetic field lines can briefly and locally connect with those in the magnetosheath, allowing the same particle population to be observed on both sides of the boundary. A mathematical model incorporating a time constant for the process resupplying particles to the open flux tube shows the observations to be reproducible at a time constant value of 46 sec, which is comparable to the half-bounce time of protons at this position.
