 note = {The Sq ionospheric currents over Kagoshima at near noon was measured by means of an optically pumped Cs magnetometer. The results obtained in the present measurement can be summarized as follows. (1) The currents flowed westward. (The north-south component were not measured.) (2) The east component of the current density was 29.7 A/Km. From the result (1), we see that the measurement was performed in the north side of the center of the global Sq current vortex. This fact can also be seen in the daily variation of the hight of the E-layer measured at the launching site, and in the daily variation of the geomagnetic field at Kanoya. Finally it must be noted that the current density obtained in the present measurement is in good agreement with that estimated from the global Sq current system, which is baced on the ground magnetic data., 資料番号: SA0124799000},
