Spectral analysis of Earth current records at South Uist, Eskdalemuir and East Anglia has revealed a harmonic frequency content in some Pi 2 spectra. The fundamental period is approximately 150 sec and in each case 4 or 5 harmonic components are present. These events were recorded during December 1969 and December 1970 and all occurred for Kp in the range 2o-4- (i.e. moderate activity). The observed waveforms could be subdivided into two groups: (a) An exponential decay from an initial impulse. (b) A dominant oscillation enclosed in a Gaussian envelope. A spectral record of one harmonic event from a Lerwick fluxgate magnetometer is presented and shows remarkable agreement with the Earth current spectrum. In each case, simultaneous worldwide recordings of Pi 2 are included.
