Abstract

Recurrent and non-recurrent galactic cosmic-ray (GCR) flux short-term variations, including three Forbush decreases, were observed with a particle detector aboard the European Space Agency mission LISA Pathfinder (LPF) orbiting around the Lagrangian point L1 between 2016 February 18 and 2017 July 3. The comparison of neutron monitor observations gathered at different geographic latitudes with contemporaneous LPF measurements provide precious clues about the energy-dependence of both recurrent and non-recurrent GCR flux short-term variations. A detailed study of the correlation between interplanetary structures and cosmic-ray short-term variations in 2016-2017 was also carried out and the results are presented here.
