摘要

In mid December 2006 several flares on the Sun occurred in rapid succession, spawningseveral CMEs and bathing the Earth in multiple solar energetic particle (SEP) events. One such SEPevent occurring on December 14 was observed at the Earth just as an interplanetary CME (ICME)from a previous flare on December 13 was transiting the Earth. Although solar wind observationsduring this time show typical energetic proton fluxes from the prior SEP event and IP shock drivenahead of the ICME, as the ICME passes the Earth unusual energetic particle signatures are observed.Measurements from ACE, Wind, and STEREO show proton flux variations at energies rangingfrom —3 MeV up to greater than 70 MeV. Energetic electron signatures from ACE show similarvariations. Within the Earth's magnetosphere Polar HIST also sees these proton flux variations atenergies greater than 10 MeV while crossing open field lines in the southern polar cap. Although nosuch variation in the energetic proton flux is observed at the GOES 11 spacecraft in geosynchronousorbit near the subsolar region, differential fluxes observed at GOES 11 and GOES 12 in the 15-40MeV energy range do show some variability, indicating the signature is observable near dawn anddusk.
