Abstract:
The solar magnetic activity cycle is currently approaching its maximum values, producing the greatest solar flares seen in the past decade. These intense solar flares have resulted in the occurrence of aurora borealis even in latitudes as low as 45 degrees. This heightened solar activity provides a unique opportunity to test and evaluate the performance of mapping techniques employed by the Ionospheric Monitoring Service to produce Total Electron Content (TEC) maps over the territory of Romania. In this study, we assess the accuracy and reliability of our mapping techniques under conditions of increased ionospheric disturbances, such as the storm that produced aurora borealis over Romania on the night of 6th to the 7th of November 2023, as the TEC maps generated during this period of elevated solar activity are crucial for understanding the impact of geomagnetic storms on communication and navigation systems. The results have been compared to maps produced by the International GNSS Service (IGS), as well as the German Aerospace Center (DLR).
