Energetic (here 30–600 keV) electron injections at the geosynchronous orbit (GEO) connected with magnetic dipolarizations were discovered long ago. Later they were associated with intrusions of bursty bulk flows (BBFs) from the tail, which deliver magnetic flux and produce dispersionless injections, afterwards forming the drifting electron cloud (DEC) at other longitudes. Up to now there is a lack of statistical studies of relationship between dipolarizations and injections; also no methods to distinguish injections from another kind of Energetic Electron (EE) flux variations, caused by drift shell crossing (DSC) and related to global magnetic reconfiguration, exist. The goal of our study was to separate injections from the DSC effect, compare EE fluxes in the injection region and DEC, and study the quantitative relationship between injections and dipolarizations. For years 2013–2017 we compared data from GOES-15 (in the injection sector) and GOES-13 four hours Eastward. Injections and DSC variations were separated based on Je(Bz) hodograms, where Je is the EE flux. EE flux values in two sectors are well correlated before injection, but are scattered at the injection peak. The best correlations of peak EE fluxes with dipolarization amplitude proxy (~0.7) are attained inside the injection region, being sufficiently lower in the DEC. Spectral characteristics in both sectors appeared similar, demonstrating spectral hardening with magnetic activity, with preferential increase of 50–200 keV electron fluxes compared to 30–50 keV channels.
