Three recent studies in the theory of micropulsations are described. Attention is given to the behaviour of the signal below the magnetosphere in the ionosphere and atmosphere, to the field line resonance problem and to hot plasma effects on magnetospheric hydromagnetic waves. In each case recent relevant observations are discussed.

A new theory of the mirror instability is developed which includes the effects of ∇B and ∇n, finite Larmor radius, and a coexisting cold plasma. It is shown that the instability becomes overstable…

Ultra low frequency waves in the magnetosphere

The behaviour of continuous pulsations pc 2–5 observed on the ground has been known for some time, and almost circularly polarised waves are predicted confirming an earlier heuristic suggestion.
