Interplanetary magnetic field

A). GMF strength versus the synodic rotational period (Po = 26.93 days) shows both sign and shape variations. This period has not varied over the last 34 years of direct measurements. Using information about measurements of the interplanetary magnetic field, Po has not varied over the 76-year time span [9-11]. Both dipole, as dominant, and quadrapole components of the field are detected in the observations (see Figure 3 and [8]). 

The Earth magnetosphere is determined by the Earth s magnetic field, as well as by the solar and interplanetary magnetic fields. In the... 

Magnetospheric plasmas are produced and heavily influenced by solar emissions and activity and by magnetic fields of the planets. Interplanetary plasmas result from solar emission processes alone. Protons in the solar wind have low densities (10—100/cm ) and temperatures below 10 to more than 10 K (1—10 eV). Their average outward kinetic energy from the sun is approximately 400 eV (58,59). The various 2ones and phenomena from the sun s visible surface to the upper atmosphere of the earth have been discussed (60—62).
