Semi-annual, annual and Universal Time variations in the magnetosphere and in geomagnetic activity: 4. Polar Cap motions and origins of the Universal Time effect
Mike Lockwood, Carl Haines, Luke A. Barnard +4
We use the am, an, as and the a-sigma geomagnetic indices to the explore a previously overlooked factor in magnetospheric electrodynamics, namely the inductive effect of diurnal mo…
The Evolution of Inverted Magnetic Fields Through the Inner Heliosphere
Allan Macneil, Mathew Owens, Robert Wicks +3
Local inversions are often observed in the heliospheric magnetic field (HMF), but their origins and evolution are not yet fully understood.Parker Solar Probe has recently observed…
On the Origin of Otho-Gardenhose Heliospheric Flux
Mike Lockwood, Mat Owens, Allan Macneil
Parker spiral theory predicts the heliospheric magnetic field (HMF) will have components of opposite polarity radially toward the Sun and tangentially antiparallel to the solar rot…
A homogeneous aa index: 2. hemispheric asymmetries and the equinoctial variation
Mike Lockwood, Ivan D. Finch, Aude Chambodut +3
Paper 1 [Lockwood et al., 2018] generated annual means of a new version of the geomagnetic activity index which includes corrections for secular drift in the geographic coordi…
Space Climate and Space Weather over the past 400 years: 1. The Power input to the Magnetosphere
Mike Lockwood, Mathew J. Owens, Luke A. Barnard +2
Using information on geomagnetic activity, sunspot numbers and cosmogenic isotopes, supported by historic eclipse images and in conjunction with models, it has been possible to rec…
