abstract:
We have developed a numerical model which describes trajectories of
protons in the given magnetospheric electric and magnetic fields.
The aim of this research is to forecast proton distribution near the
geosynchronous orbit in near real time. We use the Tsyganenko 1989
Kp=3 model and the Volland-Stern model for magnetic and electric field
models of the magnetosphere, respectively. As the boundary condition
of the electric potential, the ACE real time solar wind data are used.
We assume that protons are loaded near Xgsm=-10 earth radii in the
model magnetosphere when the ACE data show the negative IMF Bz
component. The production rate is proportional to the magnitude of the
Bz component. This model works in real time using the ACE solar wind
data.
