Global distributions of auroral hiss and VLF saucer emissions have been examined by using VLF data obtained from the three satellites, EXOS-A, ISIS-1 and -2. These VLF data were received at Syowa Station in Antarctica. From the observations of hiss and saucer emissions on five pairs of satellite paths in which the two satellites traversed the auroral zone with a time difference within one hour, it is seen that the location of the hiss and saucer emission regions do not change too much during that time. Furthermore, it is seen that the equatorward boundary of the hiss emission region is located near the position of the auroral oval statistically given by THOMAS and BOND (Planet. Space Sci., 26,691,1978) for each value of Kp index. These results suggest that the hiss and saucer emission regions exist not only statistically but also they are maintained over the time scale of one hour.
