Talk presented at U.K. Space Weather and Space Environment meeting at Sheffield on 2025-09-09

Abstract: In modern space weather operations and forecasting, information about the operational activities themselves is often lost or not efficiently exploited. This information is of particular interest in the context of "Operations to Research" and vice versa, where it can aid in enhancing the entire symbiosis of the two aspects. An important asset to have is a comprehensive database of space weather events that traces the entire chain of these events from the Sun to the Earth. The space weather operations team of the regional warning center at SIDC is developing a framework that consolidates several such events into these chains. This "Event Chain" framework aims to capture the full 'Sun-to-Earth' chain of space weather events including relevant operational information and store it in an accessible way. To achieve this, a relational database model is being developed together with a forecasting interface that integrates the entire framework into the daily operational activities at SIDC. In addition to storing such chains, it is possible to keep the evolution of objects like sunspot groups by linking observations of returning objects to eachother. Already several derived dataproducts are available currently: SIDC sunspot groups, SIDC flares, SIDC coronal holes, SIDC CMEs, forecasts (flare, high speed stream, ICME, K index). Many more events will be implemented in the near and further future to complete the full chain. To illustrate, an example will be shown of a chain captured on October 9th using the event chain framework.
