forspef thumbThe FORSPEF (FORecasting Solar Particle Events and Flares) prototype system is presented by the Space Environment Section of ESA/ETEC. The FORSPEF system was developed and is operated by The Space Research and Technology Group of IAASARS in the framework of the ESA Contract No. 4000109641/13/NL/AK "Improvement of Solar Particle Events and Flare Prediction". The FORSPEF system provides forecasting of solar eruptive events, such as solar flares with a projection to coronal mass ejections (CMEs) (occurrence and velocity) and the likelihood of occurrence of a solar energetic proton (SEP) event.

The system also provides nowcasting of SEP events based on actual solar flare and CME near real-time alerts, as well as SEP characteristics (peak flux, fluence, rise time, duration) per parent solar event. The forecasting scheme extends to 24 hours with a refresh rate of 3 hours while the respective warning time for the nowcasting scheme depends on the availability of the near real-time data and falls between 15-20 minutes. More details can be found here.
