Daytime electron density at the F1-region in Europe during geomagnetic storms

D. Buresova, J. Lastovicka, D. Altadill, and G. Miro

Abstract. This study attempts to demonstrate changes in the ionospheric F1-region daytime ionization during geomagnetic storms. The F1-region is explored using available data from several European middle latitude and lower latitude observatories and a set of geomagnetic storms encompassing a range of seasons and solar activity levels. The results of analysis suggest systematic seasonal and partly latitudinal differences in the F1-region response to geomagnetic storm. The pattern of the response of the F1-region at higher middle latitudes, a decrease in electron density, does not depend on the type of response of the F2-region and on solar activity. A brief interpretation of these findings is presented.

Key words. Ionosphere (ionospheric disturbances; mid-latitude ionosphere)
