昭和基地における電波オーロラの出現特性(日本南極地域観測隊の報告)
Radio aurora occurrences on 112 MHz observed for nearly one year from April 1970 till February 1971 at Syowa Station the Antarctic were analized. Results obtained are summarized as follows: 1) The diurnal variation in the frequency of the radio echo occurrence correlates well with the magnetic Q-ind...
