Observations of Solar Energetic Particles during September 2017 with CALET on the International Space Station; no
Abstract
A significant solar activity was registered in September 2017 at minimum of solar cycle 24. A first eruption occurring on September 6 was related to the brightest flare observed in 12 years (class X9.3). Another huge flare (class X8.2) took place on September 10. Both eruptions were associated with very fast Coronal Mass Ejections (CMEs) and produced Solar Energetic Particle (SEP) events detected by several spacecraft. In particular, the second event was energetic enough to trigger a Ground Level Enhancement (GLE). In this work we present a preliminary analysis of the September 2017 SEP events made with the CALET instrument onboard the International Space Station (ISS). We also investigate the electron enhancement associated with the geomagnetic storms occurring in the same period. Data are compared with those of other space- and ground-based detectors.
