Abstract

Magnetic fluctuations have been observed by ground observatories from the Pc5 band to the VLF band. Not all these fluctuations have been observed also in space however. The precision of satellite borne instruments, data rates and orbital characteristics have restricted observations in the past, so that only the lowest and the highest frequencies have been examined extensively. Preliminary results from recent experiments are beginning to fill this gap. Some of these new results are presented together with a review of past work.

These latest results suggest first that the large amplitude 100 to 300 sec period waves are field line resonances driven by waves generated by the motion of the magnetopause and second that ELF hiss and chorus are the result of a plasma instability in the equatorial region of the magnetosphere.
