Letter to the Editor ASTRONOMY AND ASTROPHYSICS Long-duration cosmic ray modulation from a Sun-Earth L1 orbit LETTER

Abstract

Abstract. We analyse cosmic ray hits impacting the detector system of the Coronal Diagnostic Spectrometer aboard the Solar and Heliospheric Observatory spacecraft. These observations allow us to study the modulation of cosmic rays over a 4 year period (1996-2000) running from solar minimum to maximum, from a Sun-Earth L1 Lagrangian orbit. The modulation, at the 45-50 % level is consistent with cosmic rays of energy 1 GeV
