Magnetic Field Variations in Interplanetary Space [PDF]

, 1970
Magnetic field variations and structures in interplanetary space are described and related to the sun. Discrete flare-related effects in the interplanetary medium occur within a large-scale interplanetary sector pattern related to a solar sector pattern that is ordered over a large extent in heliographic latitude and longitude.

Temporal Evolution of Sunspot Groups and Increase in the Open Flux during Solar Maximum in Cycle 24

The Astrophysical Journal
The evolution of the global solar magnetic field directly impacts the interplanetary magnetic field (IMF). During the solar maximum of Cycle 24, the monthly averaged IMF strength doubled over five Carrington rotations (CRs) in late 2014.

Interplanetary magnetic fields, their fluctuations, and cosmic ray variations [PDF]

The cause of Forbush decreases is examined using neutron monitor data and measurements of the interplanetary magnetic field. It is found that for the period examined (Dec.

Evolutionary Dynamics of Counterhelical Magnetic Flux Ropes

The Astrophysical Journal
Upon interaction, a pair of magnetic flux ropes can merge to form a new pair, each consisting of opposite helicity along their axis. Magnetic helicity along such new structures may annihilate and release the energy of the azimuthal magnetic field.

Comparison of Solar Wind Current Sheets in the Inner Heliosphere

The Astrophysical Journal
The solar wind is filled with intense current sheets (magnetic field discontinuities) that host multiple instabilities and may undergo magnetic reconnection, a basic process for plasma heating and charged particle acceleration.

Scale and Time Dependence of Alfvénicity in the Solar Wind as Observed by the Parker Solar Probe

The Astrophysical Journal
Alfvénicity is a well-known property, common in the solar wind, characterized by a high correlation between magnetic and velocity fluctuations. Data from the Parker Solar Probe (PSP) enable the study of this property closer to the Sun than ever before ...

The electromagnetic structure of interplanetary space [PDF]

A method to calculate the three-dimensional structure of the interplanetary magnetic field is presented. The integrations are based on magnetograph recordings of longitudinal magnetic fields in the solar photosphere. The program by Altschuler and Newkirk

Interplay of Large-scale Drift and Turbulence in the Heliospheric Propagation of Solar Energetic Particles

The Astrophysical Journal
The gradient and curvature of the Parker spiral interplanetary magnetic field give rise to curvature and gradient guiding-center drifts on cosmic rays (CRs). The plasma turbulence present in interplanetary space is thought to suppress the drifts; however,
