| Summary: | S-210JA-19 sounding rocket was launched on July 15,1973 from Syowa Station in order to investigate the auroral hiss in the polar ionosphere. On this day a fairly strong hiss was observed on the ground, but auroral arc was not observed. The hiss was also observed on the rocket above an altitude of 80km both in the ascending and the descending phases in the frequency range of 1-8kHz and at 30kHz. The field intensity had a maximum around an altitude of 100km. From these results, it is supposed that in some circumstances auroral hiss is generated at an altitude of about 100km by auroral particles penetrating into the polar ionosphere. |
