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 <I>Sq</I> system.
