Scientific paper

A giant pulsation (Pg), observed on two magnetometer arrays in northern Europe, has been analyzed. The integrated video records from an all-sky TV camera that was also recording pulsating aurora had an identical periodicity to the Pg. Complex demodulation analysis of the event has yielded the amplitude, phase, and polarization characteristics of the wave packet. The dominant east-west (D) component wave signature in amplitude and phase suggests that this Pg has guided poloidal mode characteristics. Equatorial mass-density calculations show that the Pg is most likely to be a second-harmonic oscillation. The bounce resonance instability with 17-keV protons is discussed as a possible candidate for the generation of the Pg.
