The solar energetic particle (SEP) event from 26 Dec 2013 was a so-called widespread event observed by multiple spacecraft. The two STEREO and one close to Earth spacecraft spanned a total longitudinal angle of 210 degrees at that time. Together with the 25 Feb 2014 (Lario et al., 2016, Klassen et al., 2016) this is the widest event ever observed with the STEREO spacecraft. Unusually long-lasting SEP anisotropies together with […]

We developed an innovative approach by studying each Earth-directed event leading to a storm sudden commencement (SSC) in the magnetosphere during 2002 (maximum activity of Cycle 23). This unprecedented, comprehensive study consists of: i) starting from the list of 32 SSCs listed by the International Service of Geomagnetic Indices (ISGI) of the Observatory de l’Ebre, ii) linking each SSC to a CME, iii) filling in the observational gaps along the […]
