Effects of solar flares on ionospheric TEC over Iceland before and during the geomagnetic storm of 8 September 2017
The effects of solar flares on ionospheric total electron content (TEC) over Iceland before and during the geomagnetic storm of September 8, 2017 were studied. Global Positioning Syste (GPS)-TEC data were obtained from dual-frequency GPS sites operated by the University NAVSTAR Consortium at Dyna (6...
