What happens when the geomagnetic field reverses?

, 2012
During geomagnetic field reversals the radiation belt high-energy proton populations become depleted. Their energy spectra become softer, with the trapped particles of highest energies being lost first, and eventually recovering after a field reversal ...

Magnetic field and plasma parameters for magnetic clouds in the interplanetary medium [PDF]

Geofísica Internacional, 2000
For a set of 16 magnetic cloud events measured at 1 AU we investigated the magnetic field and plasma parameters in order to characterize the pressure differences between the structure and the environment. The asymmetry profile of the magnetic cloud field

Fractal structure of the interplanetary magnetic field [PDF]

Under some conditions, time series of the interplanetary magnetic field strength and components have the properties of fractal curves. Magnetic field measurements made near 8.5 AU by Voyager 2 from June 5 to August 24, 1981 were self-similar over time ...

Multiwavelength Study on Solar and Interplanetary Origins of the Strongest Geomagnetic Storm of Solar Cycle 23

, 2011
We study the solar sources of an intense geomagnetic storm of solar cycle 23 that occurred on 20 November 2003, based on ground- and space-based multiwavelength observations.

Variation with interplanetary sector of the total magnetic field measured at the OGO 2, 4, and 6 satellites [PDF]

Variations in the scalar magnetic field (delta B) from the polar orbiting OGO 2, 4, and 6 spacecraft are examined as a function of altitude for times when the interplanetary magnetic field is toward the sun and for times when the interplanetary magnetic ...

Study of Interplanetary Magnetic Field with Ground State Alignment

, 2012
We demonstrate a new way of studying interplanetary magnetic field -- Ground State Alignment (GSA). Instead of sending thousands of space probes, GSA allows magnetic mapping with any ground telescope facilities equipped with spectropolarimeter.
