Energetic particle microsignatures of Saturn's satellites

During Voyager's 1980 and 1981 encounters with Saturn, the low energy charged particle experiment observed satellite microsignatures in ions and electrons. Each of the five major satellites within Titan's orbit were associated with at least one absorption feature in the high time resolution data. Microsignatures are usually observed in the corotational wake region within about 25 deg in azimuth of a satellite, and do not generally occur at times predicted by a centered, aligned dipole. A better predictive model seems to be that of an aligned, axisymmetric field with significant quadrupole and octupole terms.
