Contribution

It provides a detailed analysis of mid-latitude ionospheric responses to geomagnetic storms during Solar Cycle 25, focusing on Turkey and identifying specific storm-related anomalies.

Findings

Short-term enhancements in electron content during storms

Distinct features like Storm Enhanced Density observed in mid-latitudes

Correlation between geomagnetic activity indices and ionospheric irregularities

Abstract

The interaction between solar activity and Earth's magnetosphere magnetosphere-ionosphere system often results in geomagnetic storms that disturb ionospheric electron density. In this study, we analyse the ionospheric response to selected geomagnetic storm events during the Solar Cycle 25, focusing on the mid latitude region of Earth, including Turkey. Hourly Kp and Dst indices obtained from the OMNI database are compared with global TEC maps provided by NASA CDDIS. Storm time anomalies include short term enhancements and irregularities in electron content, correlated with geomagnetic activity. Unlike equatorial regions, mid-latitude ionospheric responses exhibit distinct features such as Storm Enhanced Density (SED). These findings emphasize the importance of continuous space weather monitoring for navigation and communication systems.
