We investigate the characteristics of rapid geomagnetic variations at high latitudes based on the occurrence of large time derivatives of the horizontal magnetic field (dH/dt exceeding 1 nT s−1). Analysis of IMAGE magnetometer data from North Europe in 1983–2010, covering more than two solar cycles,...
