Nearly simultaneous data from the Chatanika radar, the TRIAD satellite, and the IMS Alaska meridian chain of magnetic and auroral observations are utilized to examine the spatial relationship among auroras, field-aligned currents, ionospheric electric fields, and conductivities in the westward electrojet in early morning hours. The westward electrojet is found to be dominated by one of two different quantities, depending on latitudinal locations in this local time sector. The poleward half of the electrojet is governed by a relatively intense southward electric field. On the other hand the Hall conductivity is the dominant factor in controlling the electroject current in the equatorward half. The electroject center appears to be located within the region of the upward field-aligned current. Major auroral activity is present only in the equatorward half of the electroject in which the upward field-aligned current prevails, although it appears that the latitudinal variations of the conductivity and current intensity are not well related within that region.
