A VLF receiver at Siple Station during 1975 recorded the Doppler shift on Whistler mode signals from NAA, Cutler, Maine. An initial analysis of the data shows that signals could be received at any hour of the day during Southern Winter. On the dayside, the Doppler shift frequently showed large oscillations, due to pulsations in the Pc4--5 range. On average, a well-defined diurnal pattern of shifts was found. This pattern supports some features of recent measurements of the convection electric field in the plasmasphere, and also suggests that the quiet plasmasphere near L=3 refills by ~1017el/m2/day for the entire tube between the 1000 km levels.
