Comparative Study of Magnetic Pc-Type Pulsations at Low and High Latitudes (I) : Pc 1 Pulsatins (d. ULF Waves in the Magnetosphere) (Proceedings of the Second Symposium on Coordinated Observations of the Ionosphere and Magnetosphere in the Polar Regions : Part I)
Statistical features of Pc 1 pulsations were studied on the basis of data obtained at a low-latitude station, Memambetsu in Japan and at a high-latitude station, Syowa Station in Antarctica, for the period of February 1977 to January 1978. The low-latitude Pc 1 shows distinct difference from the hig...

Summary: | Statistical features of Pc 1 pulsations were studied on the basis of data obtained at a low-latitude station, Memambetsu in Japan and at a high-latitude station, Syowa Station in Antarctica, for the period of February 1977 to January 1978. The low-latitude Pc 1 shows distinct difference from the high-latitude one in diurnal and seasonal variations of frequency of occurrence, mean and repetition periods and dependencies on general geomagnetic activity (Dst and Kp). A source region associated with the low-latitude Pc 1 may be located further inside in the magnetosphere than that associated with the high-latitude one |
