Paper Abstract

We investigate the atmospheric emission variations at mid-latitudes during geomagnetic disturbances in connection with the state, dynamics and latitudinal displacement of the auroral oval, the main ionospheric trough (MIT), and of the plasmapause. For the location of the ISTP SB RAS Geophysical observatory (52°N, 103°E) there are several types of atmospheric emission variations, corresponding to different levels of geomagnetic disturbance, which are caused by various mechanisms and sources: wave-like fluctuations of 630 nm emission superimposed on the regular night-time behavior, significant enhancements of 630 nm emission that substantially disturb the night-time behavior of this emission, disturbances of 558 nm, 630 nm and 391.4 nm emissions of the auroral type, and SAR-arcs. Magnetospheric and ionospheric structures (plasmasphere, plasmapause, equatorial boundary and MIT center, etc.) that are the sources for or determine the character of atmospheric emission variations, are placed in correspondence with each of the identified types of atmospheric emission variations. It is intended to use the recorded atmospheric emission variations to monitor the ionspheric-magnetospheric structures during moderate and high levels of geomagnetic disturbances.
