FORecasting Solar Particle Events and Flares

The FORSPEF Tool provides notifications on the Occurrence and the Expected Characteristics of forthcoming Solar Energetic Particle (SEP) radiation storms, either for a given solar flare (SF) or for a Coronal Mass Ejection (CME), with known characteristics.

All notifications are issued when the calculated probability of SEP Occurrence is >=0.25 . The typical nowcast warning window of the tool is of the order of ~15-20 minutes, for warning based on SF data. For warnings based on CME data, the typical warning window is of the order of ~6 hours.
