• VLF chorus observed in geomagnetically quiet condition by an Antarctic rocket S-310JA-1 is discussed in detail in comparison with that observed on the ground (Syowa Station). The chorus intensity at the rocket altitudes was roughly E=18μV/m and H=5×(10)^<-12>T for a bandwidth of 50Hz which proved the chorus propagation being in the whistler mode. The upper cutoff frequency of the chorus spectra observed on the ground was always lower than that observed by the rocket. The difference of the upper cutoff frequency is interpreted by the frequency characteristics of both the effect of perfect reflection of the chorus at the bottom of the ionosphere and the collisional damping. Static noise phenomena were also observed by the same rocket which will be reported in our future paper.
