- Аннотация: We have studied the global magnetospheric structure and its dynamics during 2009-2012 using satellite measurements. We determine the mean position of the outer radiation belt (ORB) boundaries at the Earth surface using regular measurements of E > 200 keV electron uxes onboard Coronas-Photon since March till November 2009 and E > 100 keV electron uxes onboard Meteor-M #1 since November 2009 till May 2012. These low altitude polar satellites crossed the external boundaries of ORB approximately every 1.5 hrs. It was obtained that the high-latitude ORB boundary is controlled by both geomagnetic (internal) and magnetospheric magnetic elds. The extremely quiet conditions allowed us to separate the e ects induced by internal and external factors. It has been found that at the ionospheric level the high-latitude boundary of ORB rotates with the Earth but slightly shifts to the night side due to large-scale magnetospheric currents. Variation of ORB boundaries have been determined to depend on UT (universal time). By adding disturbed periods we can catch the dependence between dst-index and the boundary sizes. It was found that the boundary enlarges while dst decreases
