Resumo

In this paper we study the relationship between Interplanetary Coronal Mass Ejections (ICMEs) and the muon count rate decreases detected of the Muon Detector Network on November 6-12, 2004. The Muon Detector Network is composed by the detectors installed at Nagoya (Japan), Hobart (Australia) and the prototype detector installed at the "Observatório Espacial do Sul - OES/CRSPE/INPE-MCT", located in São Martinho da Serra, RS, Brazil. With the muon count rate observed by the Muon Detector Network, we will be able to observe, in the future, the direction in which a given ICME moves, and with that, we will be able to calculate their angle of incidence on the Earth. Also, with this muon network, we will be able to send alerts of up to 12 hours before the arrival of a shock or an ICME. The Space Weather forecast method using cosmic rays will be a very important tool because it provides a forecast with good antecedence. (AU)
