On December 2, 1983, the HILAT satellite trajectory was approximately aligned with the noon-midnight meridian while crossing the northern polar cusp/cleft region. During that time we observed (1) an increase in scintillations of radio signals, (2) strongly variable fluxes of precipitating low-energy electrons, (3) gradients in the thermal ion density, (4) fluctuations in the east-west component of the ion drift velocities superimposed on the noon sector convection pattern, and (5) field-aligned currents. In the region corresponding to the highest level of radio scintillations we also detected fluctuations in electron fluxes on a time scale of half a second superimposed on a low-energy inverted-V event.
