Abstract

Auroral kilometric radiation (AKR) observations by Polar and Geotail are compared with the auroral electrojet index for the January 1997 magnetic cloud event. These two-spacecraft measurements are complementary in covering the AKR emission cones throughout the event and, together, reasonably represent the auroral electrojet A_E index. We point out, however, limitations of both the AKR index and the A_E index in providing truly global measurements of substorm activity.
