The behaviour of electron temperature under non-stationary conditions in dependence on geomagnetic latitude

Summary The electron temperature was monitored using a radiofrequency probe situated on the board of satellite INTERCOSMOS-8 from 30th Nov. to 25th Dec., 1972. All data were obtained under quiet geomagnetic conditions K_p<2⁺. The processing of data enabled us to compare the behaviour of the electron temperature T_e under non-stationary conditions of local sunrise and sunset for various geomagnetic latitudes. The results showed a different behaviour of the electron temperature in mid-latitudes and in the region of the magnetic equator in dependence on angle x.
