The reported -4-month ''season'' for observation of Jovian electron events at 1 a.u. is shown to be a plausible consequence of field-line random walk in the solar wind. Values of the field-line random-walk coefficient deduced earlier in connection with observations of solar protons, photospheric supergranulation and the interplanetary magnetic-field power spectrum, lead to an approximate value for the spread of Jovian electrons at 1 a.u. which corresponds to a -4-month duration of events. This model is consistent with a point source at Jupiter.
