Large changes of the magnetic field associated with magnetic perturbation events (MPEs) with amplitudes |Î B| of hundreds of nT and 5- 10Â min duration have been frequently observed within a few hours of midnight. This study compares the statistical location of nighttime MPEs with |dB/dt| - ¥ 6Â nT/...
