The paper deals with the quality assessment and the analysis of possible corrections of the empirical model of the shape and position of the high-latitude boundary of the Earth’s outer radiation belt [2] using the full dataset on the electron fluxes with energy above 100 keV measured in the recent 5 years at the orbit of the Meteor-M No. 2 satellite. The high-latitude boundary of the Earth’s outer radiation belt at the altitude of 800 km is approximated with an elliptic curve in the geomagnetic coordination system with the parameters depending on the universal time (UT effect) and geomagnetic activity (Dst index). The full dataset of intersections of the high-latitude boundary of the Earth’s outer radiation belt by the Meteor-M No. 2 satellite in 2014–2019 was constructed to test the model. The database was utilized to determine errors of the model for various geomagnetic conditions in the magnetosphere and at different magnetic longitudes and to propose ways for its modernization.

AbstractWe use low frequency geomagnetic field measurements at two Antarctic stations to statistically investigate the longitudinal location of the polar cusp. The two stations are both located in the polar cap at a geomagnetic latitude close to the cusp latitude; they are separated by one hour in magnetic local time. At each station the Pc5 power maximizes when the station approaches the cusp, i.e. around magnetic local noon. The comparison between the Pc5 power at the two stations allows to determine the longitudinal location of the cusp. Our analysis is conducted considering separately different orientation of the interplanetary magnetic field. The results, which indicate longitudinal shifts of the polar cusp depending on the selected conditions, are discussed in relation to previous studies of the polar cusp location based on polar magnetospheric satellite data.
