Abstract: The Solar Influences Data analysis Centre (SIDC) based at the Royal Observatory of Belgium has a long term experience in space weather service provision, combining various modelling with solar observations. The Space Weather OPerations (SWOP) team within the SIDC has more than 20 years of experience in space weather forecasting and product developments, and since 2019 is heavily involved in 24/7 operational space weather service provision to aviation within the framework of PECASUS consortium. Combining our daily space weather forecasting and operational service provision efforts with model expertise provided in-house or by partnering institutions we propose to present our perspective on the recent severe space weather event, leading to multiple periods of extreme geomagnetic conditions with diverse impacts. We will follow the event from the solar surface origin to the impacts on Earth, combining solar observations with prediction models and including modelled and observed impacts regarding problems with high-frequency radio communications, navigation and radiation environment. We will briefly mention other impacts, such as observed auroras over Belgium, as well as some reported power outages over US.
