Scientific paper

The behavior of the subauroral ionosphere at L equals 4 during quiet and geomagnetically disturbed periods is described in terms of ionospheric total electron content, F-region peak density and equivalent slab thickness. Diurnal curves of monthly median quiet time behavior show that the total electron content and F-region peak density are usually lower at subauroral latitudes than at midlatitudes. The layer thickness is found to be larger during the day than at night at both locations except in winter, and nearly always larger at L equals 4 than at midlatitudes. During geomagnetic storms, nighttime total electron content increases and smaller total electron content and density peaks which are cut off earlier relative to those in the midlatitude atmosphere are observed in the L equals 4 subauroral atmosphere. These effects are attributed to equatorward shifts in auroral particle induced ionization and the contraction of the plasmasphere, respectively. Slab thickness increases during storms are related to storm induced heating and auroral precipitation effects.
