Attention is given to Siple Station, Antarctica observations of Pi 1 magnetic pulsations which contain an unusual class of fluctuations characterized by large amplitude, 0.2-1.0 nT/sec, one-sided pulsations in photometer/magnetometer valves, with variable direction. The pulsations are 2-10 sec wide, and occur in an irregular train of pulses that lasts sporadically, up to an hour. These Pi 1 pulsations are presently interpreted to be the result of local enhancements in ionospheric and field-aligned currents associated with precipitating electrons that are responsible for the associated pulsations in auroral luminosity. No evidence has been found of a sinusoidal component of these magnetic pulsations which travels as a wave in the magnetosphere.
