Ionosphere response to space weather events on 21–23 March 2017 in the central region of Europe

The paper presents the results of experimental studies of the manifestations of ionospheric storms in the Central European region during the geomagnetic storm on March 21–23, 2017. The time dependences of the critical frequency of the ionospheric F2 layer foF2 and the F2 peak height hmF2, the altitude-time dependences of the electron temperature T e , ion temperature T i ; electron density N e and vertical ionospheric plasma drift velocity V z in the altitude range 190–500 km for disturbed and reference days were obtained. The minor storm was featured by the presence of three negative phases of ionospheric disturbance.
