A high-sensitive VLF wave observation has been carried out using the stratospheric balloon (B_<15>-4N) launched from Esrange in Sweden on December 9,1982. The VLF receiving system installed on the balloon has been equipped with a large one-turn loop antenna attached along the balloon surface. During the level flight at an altitude of 30km, power line harmonic radiations and periodic emissions with the repetition period of about 2.7s have been observed in connection with the development of an auroral substorm. In this paper, spectral characteristics of these emissions are examined based on the dynamic spectral analysis in order to clarify the feature of the wave-particle interactions relating to the generation of these emissions.
