The Earth ionosphere, a natural plasma, is located approximately 60 km to 1100 km above
the Earth. Ionospheric storms develop due to geomagnetic storms. In this study, we looked
at the changes in ionospheric parameters recorded in the stations at the central latitude
and the ionospheric storms caused by the geomagnetic storm of July 16, 2017, which was
formed by solar wind resulting from coronal mass ejection. The change of ionospheric
parameters has a crucial role in space weather and communication. The negative
ionospheric storm causes serious problems in ground-based HF radio communications,
while the positive ones can cause serious problems such as time delay in satellite
communication and navigation, range error and glare. In this study, the GIRO stations
were confirmed and interpreted by ionospheric distribution and types via ionogram data
from PQ052, RO041, VT139. Ionospheric irregularities during the geomagnetic storm
were analyzed using the lower quarter-upper quadrant method
