The effect of geomagnetic activity changes on the ionospheric critical frequencies (foF2) at magnetic conjugate points

E Timoçin, İ Ünal, Y Tulunay, ÜD Göker - Advances in Space Research, 2018 - Elsevier
In this work, we investigate the possible effects of geomagnetic activity on the ionospheric
critical frequencies (foF2) in geomagnetic conjugate points. For this purpose, hourly foF2 …
