000007645 520__ $$aSince its operational launch on November 7, 2019, the Pan-European Consortium for Aviation Space weather User Services (PECASUS) has been providing real-time space weather monitoring and issuing ICAO-compliant advisories to the global aviation sector. PECASUS has played a pivotal role in mitigating aviation risks associated with HF communication disruptions, GNSS degradation, and increased radiation exposure at flight altitudes. We will present an overview of selected, significant geomagnetic storms (October and May 2024) as observed via the operations of PECASUS. We provide a brief history of these events (source, evolution) and analyse their effect via the PECASUS advisories. In addition, we will also discuss their impact on ground- and space-based infrastructure, highlighting the importance of space weather monitoring and forecasting. The results showcase how geomagnetic storm analysis can contribute to improving aviation safety. Finally, we will address ongoing and future developments within PECASUS, aiming to further improve the services provided.
