Previous Io flyby passes had been at solar phase angles near noon (I0) near 1045 LT (I24, I25) and near 0900 LT (I27). These passes showed a progression of behavior with the solar phase angle. On I0 the ion cyclotron waves had been peaked very strongly near the SO2 ion cyclotron frequency inbound when the spacecraft was above the daylit hemisphere of Io but were very broad in extent. Above the dark side of Io the wave frequency switched to that of SO. On later passes (but at earlier solar phase angles) the wave amplitude was less than on I0 and multiple ion cyclotron waves seen simultaneously in narrow bands. Thus on the I31 pass we expected to observe weak narrow-banded signals. Instead the signals are as strong as on the passes near 1030 LT and they are quite broad in frequency extent. The strength of the waves may be explained by the trajectory of Galileo that remained close to the edge of the co-rotation wake. The broad spectrum of waves suggests the presence of ions from about the mass of sulfuric acid (98) to that of sulfur (32). Over this whole band the waves are left-hand elliptically polarized and propagate at a small angle to the field.
