| Abstract: | Precipitation of electrons with energies of 0.3–1.5 MeV has been analyzed based on the CORONAL-F satellite data at polar latitudes
of the Northern Hemisphere on December 13, 2003. The instants of electron precipitation have been compared with the ground-based
observations of geomagnetic disturbances and auroras near the satellite orbit projection. It has been indicated that precipitation
of energetic electrons in the high-latitude nightside sector is accompanied by the simultaneous development of bay-like magnetic
field disturbances on the Earth’s surface and the appearance of riometer absorption bursts and Pi3 geomagnetic pulsations,
and auroras. |
