Latitudinal Dependence of Cosmic Rays Modulation at 1 AU and Interplanetary Magnetic Field Polar Correction [PDF]
Advances in Astronomy, 2013 The cosmic rays differential intensity inside the heliosphere, for energy below 30 GeV/nuc, depends on solar activity and interplanetary magnetic field polarity.

Active Regions and the Interplanetary Magnetic Field [PDF]
Symposium - International Astronomical Union, 1968 The relation of solar active regions to the large-scale sector structure of the interplanetary field is discussed. In the winter of 1963–64 (observed by the satellite IMP-1) the plage density was greatest in the leading portion of the sectors and lesser in the trailing portion of the sectors. The boundaries of the sectors (places at which the direction

On the intermittent character of interplanetary magnetic field fluctuations [PDF]
Physics of Plasmas, 2007 Interplanetary magnetic field magnitude fluctuations are notoriously more intermittent than velocity fluctuations in both fast and slow wind. This behaviour has been interpreted in terms of the anomalous scaling observed in passive scalars in fully developed hydrodynamic turbulence.

The mean solar magnetic field as an indicator of the interplanetary magnetic field [PDF]
Annals of Geophysics, 1996 The Mean Solar Magnetic Field (MSMF) measured daily by ground based observations at the Standford Observatory shows similar structures like the Interplanetary Magnetic Field (IMF) near the Earth about 5 to 7 days later.

Cosmic rays in the interplanetary magnetic fields [PDF]
Icarus, 1968 Abstract The propagation of cosmic rays in the regular and random interplanetary magnetic fields transferred by the clouds of the interplanetary plasma is considered. The equation for the distribution function is obtained. This equation is discussed in the diffusion and drift approximations and explicit solutions for some particular cases are found ...

Tracing the heliospheric magnetic field via anisotropic radio-wave scattering [PDF]
Scientific ReportsAstrophysical radio sources are embedded in turbulent magnetised environments. In the 1 MHz sky, solar radio bursts are the brightest sources, produced by electrons travelling along magnetic field lines from the Sun through the heliosphere.

Interplanetary Causes and Impacts of the 2024 May Superstorm on the Geosphere: An Overview [PDF]
The Astrophysical JournalThe recent superstorm of 2024 May 10–11 is the second largest geomagnetic storm in the space age and the only one that has simultaneous interplanetary data (there were no interplanetary data for the 1989 March storm). The May superstorm was characterized

On an interplanetary magnetic field [PDF]
Journal of Geophysical Research, 1955 Considerations suggesting the existence of an interplanetary magnetic field are presented. Such a field would not exceed about 5×10−8 gauss, and its presence can explain the observed cutoff in the primary cosmic-ray momentum spectrum. A field existing within the earth's orbit can account for all or part of the observed solar-terrestrial time delays in ...
