The shape of the Sq current system

Abstract. Many years ago Mayaud (1965) suggested that a tilted, rather than symmetric, current system may be responsible for the form of daily magnetic variations near the focus of the current system. With arrays of magnetometer stations, both in Australia and in Europe, it is now demonstrated that such tilted systems do exist at certain times. At other times the magnetic variation near the focus is deformed by a previously reported extra morning current system which is apparently unconnected to the regular Sq system.
