In this work we present a method of automatic detection of the high latitude boundary of the Earth’s outer van Allen belt (HLB). The two-pass algorithm is based on detection of the highest monotone electron flux grow and decay at high latitudes for 30-second and 1-second resolution data. The processing algorithm is based on analyzing time profiles of charged particle fluxes (electrons, 100-200 keV) measured at low altitude polar circular orbits of the Coronas-Photon, Meteor-M1 and Meteor-M2 spacecraft. We have enhanced our empirical model of the HLB for quiet periods to describe a substantial subset of disturbed periods. We have investigated a realations with the L McIlwain coordinate values for each dst interval. We have also conducted analyses of the dependence of the mean HLB position depending on the DST index during 2014-2016. The similar dependence of HLB position on Kp was also obtained.
