Dual-Lobe Reconnection and Horse-Collar Auroras
Milan, Stephen Eric; Carter, Jennifer Alyson; Bower, G.E.; Imber, S.M.; Paxton, Larry J.; Anderson, Brian J.; Hairston, Marc; Hubert, Benoit (Journal article; Peer reviewed, 2020)We propose a mechanism for the formation of the horse-collar auroral configuration during periods of strongly northward interplanetary magnetic field (IMF), invoking the action of dual-lobe reconnection (DLR). Auroral ... -
Solar Cycle and Solar Wind Dependence of the Occurrence of Large dB/dt Events at High Latitudes
Milan, Stephen Eric; Imber, S.M.; Fleetham, A.L.; Gjerløv, Jesper (Journal article; Peer reviewed, 2023)We investigate sharp changes in magnetic field that can produce Geomagnetically Induced Currents (GICs) which damage pipelines and power grids. We use one-minute cadence SuperMAG observations to find the occurrence ...
