Linking two consecutive non-merging magnetic clouds with their solar sources
(American Geophysical Union, 2009-12)
On 15 May 2005, a huge interplanetary coronal mass ejection (ICME) was observed near Earth. It triggered one of the most intense geomagnetic storms of solar cycle 23 (Dstpeak = −263 nT). This structure has been associated ...
Periodicidades no fluxo de raios cósmicos e análise de choques interplanetários
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2010-01-08)
Muons and neutrons that reach the Earth surface with high energy constitute a particles’ group called secondary cosmic rays. In order to study the flux of this particles data from muons and neutrons stations are used. The ...
20 Years of ACE Data: How Superposed Epoch Analyses Reveal Generic Features in Interplanetary CME Profiles
(Blackwell Publishing Ltd, 2020-10)
Interplanetary coronal mass ejections (ICMEs) are magnetic structures propagating from the Sun's corona to the interplanetary medium. With over 20 years of observations at the L1 libration point, ACE offers hundreds of ...
VARIATIONS OF THE MUON FLUX AT SEA LEVEL ASSOCIATED WITH INTERPLANETARY ICMEs AND COROTATING INTERACTION REGIONS

Statistical analysis of discontinuities in solar wind ace data and comparison with intermittent mhd turbulence
(IOP Publishing, 2009-12)
The comparison between Advanced Composition Explorer (ACE) solar wind data and simulations of magnetohydrodynamic (MHD) turbulence shows a good agreement in the waiting-time analysis of magnetic field increments. Similarity ...
Statistical Analysis of Extreme Electron Fluxes in the Radiation Belts
(Cambridge University Press, 2018-07)
The main aim of this work is to study the frequency of extreme Space Weather events, in particular to analyse the tails of the daily averaged electron fluxes distribution function for different channels of energy between ...
