Comment on ‘Sunday decreases in magnetospheric VLF wave activity’ by C. G. Park and T. R. Miller

ground should not be used to draw general conclusions on either the characteristics of magn•etospheric plasma waves or their influence on the radiation belts.ARE THE DETECTED EMISSIONS CHORUS?We first consider whether the wide band signals detected at Siple are indeed dominated by 'chorus' emissions originating from the outer magnetosphere.This point is fundamental to the subsequent analysis by Park and Miller, who assume that the temporal variation in the monitored wide band amplitude
