SIR-HUXt -- a particle filter data assimilation scheme for assimilating CME time-elongation profiles
Luke Barnard, Mathew Owens, Chris Scott +2
We present the development of SIR-HUXt, the integration of a sequential importance resampling (SIR) data assimilation scheme with the HUXt solar wind model. SIR-HUXt is designed to…
Evolving Solar Wind Flow Properties of Magnetic Inversions Observed by Helios
Allan R Macneil, Mathew J Owens, Robert T Wicks +1
In its first encounter at solar distances as close as r = 0.16AU, Parker Solar Probe (PSP) observed numerous local reversals, or inversions, in the heliospheric magnetic field (HMF…
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 Solar Corona during the Total Eclipse on 16 June 1806: Graphical Evidence of the Coronal Structure during the Dalton Minimum
Hisashi Hayakawa, Mathew J. Owens, Michael Lockwood +1
Visible coronal structure, in particular the spatial evolution of coronal streamers, provides indirect information about solar magnetic activity and the underlying solar dynamo. Th…
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…
