Plasma emissions have been detected mainly in two regions. In the auroral region, the auroral hiss is associated with the electron precipitation. The hiss occurrs in two frequency regions. One exists below the minimum of f_p^- or f_g^- where f_p^- and f_g^- are the plasma and cyclotron frequenceis of electrons, respectively and the other extends to above it. The hiss which extends to above the minimum of f_p^- or f_g^- is correlated with the inverted V electron precipitation with a peak energy of a few keV to 10 keV. In the equatorial region, a hiss has been also observed. Two different modes coexist in the hiss. One is a usual whistler mode observed in geographically limited regions. The other is a UHR wave which sometimes continues to be observed in the polar regions., 資料番号: SA0166527000}, pages = {87--98}, title = {科学衛星 KYOKKO によるプラズマ波動の観測}, volume = {2}, year = {1982} }
