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}, pages = {241--250}, title = {低緯度および高緯度におけるPc型地磁気脈動の特性の対比 (I)(d.磁気圏内のULF波動)(第2回極域における電離圏磁気圏総合観測シンポジウム : Part I)}, volume = {68}, year = {1980}, yomi = {クワシマ, マサユキ and トヤ, タケシ and カワムラ, マコト} }
