More magnetic flux crosses the equatorial plane on the dawn and dusk flanks of the tail than near midnight, but no evidence is found for a dependence on the interplanetary magnetic field sector polarity. Field magnitudes within 3 RE of the equatorial plane near dawn are more than twice as ...
The second: the solar magnetic field (MFs) from synoptic magnetographs. The third: CI measured at the east limb. And the fourth (bottom) panel: CI at the west limb. The vertical thick dashed lines show the minimum times of the solar cycles. Full size image Cross-correlation analysis is ...
This is not always true, however, the IMF may reverse without any apparent effect at the equator. Furthermore, large equatorial field perturbations are sometimes observed when the IMF Bz is large and southward but not varying drastically. In this latter case the equatorial perturbations start ...

Significant populations of particles at keV–MeV energies, well above the energy of the thermal population, are found in allmagnetospheres. Theenergeticparticles are largely trapped in long-lived radiation belts (summarized inTable 4) by the strong planetarymagnetic field. Where do these energetic pa...
Electric fields in the equatorial ionosphere derived from individual CHAMP satellite orbits In this work we use CHAMP satellite-derived latitudinal current profiles of the day-time EEJ in order to estimate the eastward electric field at all longitudes, seasons, and day-side local times. We have ...
Transverse, low-frequency oscillations in the magnetic field have been recorded in the equatorial plane at 6.6 R E (earth radii) with the UCLA magnetomete... WD Cummings,RJ O'Sullivan,Coleman, P. J., Jr. - 《Journal of Geophysical Research》 被引量: 904发表: 1969年 In situ monitoring ...
For example, particle dissipation at low altitudes could produce a loss cone distribution observed on the same field line in the equatorial region (e.g., Thorne et al. 2010). Pc3–5 ultra-low-frequency waves Low-frequency magnetic field variations observed in the inner magnetosphere are ...
Planet Magnetic Field Assuming that each planet's magnetic field has the simplest structure, a dipole, we can characterize the magnetic properties by noting the equatorial field strength (B0) and the tilt of the axis with respect to the planet's spin axis....
