Resumo
© NuFact 2015. All rights reserved.We present a Forbush decrease (FD) event observed with CARPET cosmic ray detector operating at EL Leoncito (CASLEO San Juan, Argentinian) since 2006. The FD occurred from 8 to 16 on March 2012, it was caused by a couple of CMEs launched on 2012 March 7 associated with a X5 solar flare. CARPET data, after correcting by atmospheric variations, shows a FD with intensity ∼ 5%, which started just at the time of interplanetary shock that caused a intense geomagnetic storm. The FD event detected by CARPET showed a temporal evolution very similar to the one observed by Neutron Monitor of Rome detector. The onset of FD events occur few hours before geomagnetic storms, so statistic study of the correlation between their characteristics and storm intensity can be used to forecast geomagnetic activity level.
