Analysis of the Complex Forbush Decreases of June 2015
Abstract
We investigated the sudden increase of the counting rates observed by muon telescopes during the main phase of the June 20, 2015 Forbush decrease. We analyzed the probability that this peak was caused by a shock reacceleration of solar energetic particles accelerated by the solar flare occurred on June 22, 2015. To study this event, we used ground level cosmic ray detectors, GOES proton intensities, observations of the geomagnetic activity index (Dst) and interplanetary magnetic field data observed by ACE and WIND spacecraft available from the OMNI database.
