Resumo

A method of exhibiting the magnetic daily variations using contours based on running means can give a more precise indication of the seasonal changes in daily variation than conventional methods. This method is applied to the variations at Koror, which are of particular interest owing to Koror's location, almost exactly on the magnetic dip equator. The contour charts give new evidence (a) that the ionospheric current shifts with the seasons and (b) that throughout the IGY period the equatorial electrojet was located to the north of Koror. This indicates that the electrojet does not form a barrier between the northern and southern current systems.
