Abstract: Since many years the International Civil Aviation Organization (ICAO) has requested the development of space weather services tailored to the needs of civil aviation sector. In 2019 three world centres started to provide continuous 24/7 near-real time space weather services to aviation, namely the NOAA Space Weather Prediction Centre (SWPC), the Australia-Canada-France-Japan consortium (ACFJ) and the Pan-European Consortium for Aviation Space Weather User Services (PECASUS). Later on, a fourth centre, the China-Russia-Consortium (CRC), joined the service provision in 2021. As part of PECASUS the role of the Solar-Terrestrial Centre of Excellence (STCE) is to serve as a primary data hub unit for various data and models provided by partnering members, to continuously monitor the space weather conditions and generate the content of space weather advisories for aviation. To estimate the space weather conditions and possible impacts to aviation the STCE makes further use of its internal space weather monitoring and forecasting capabilities and also serves as an internal data provider for GNSS services and supporting radiation alert products. This work aims to present the lessons learned from the first 5 years of 24/7 near-real time operational space weather service provision to aviation within STCE and PECASUS. We will review the issued space weather advisories and showcase the relevant aviation impacts for selected events. We will further discuss the coordination between the four global centres and comment on preliminary end-user feedback. Finally we will list some of the open challenges in the service provision and envisioned steps towards future improvements.
