Developing an SEP Advanced Warning System

A new activity to develop an SEP Advanced Warning System (SAWS) has been initiated in July 2017. The activity named ASPECS (Advanced Solar Particle Events (SPEs) Casting System) will take a modular approach to ingest all relevant solar and in-situ measurements in order to forecast the onset of SPEs and their characteristics. The system will provide forecasts 2-3 days in advance based on solar magnetogram data with updates as more information becomes available and a possible particle storm approaches. Therefore the forecast will improve as we get closer to the event - just like weather forecasting on Earth!
