“…Solar activity produces coronal mass ejections (CMEs) that, if directed towards Earth, may cause geomagnetic storms on Earth, possibly damaging, for example, electronic equipments, electric power line systems and geospatial instruments. Some studies have shown that a systematic reduction on muon counts of about 2% can be detected 4-8 hours ahead of a possible geomagnetic storm [Munakata et al, 2000], [Frigo et al, 2007], allowing accurate and reliable Space Weather forecasting. This forecast can be used to avoid important losses, mainly when solar activity reaches its maximum activity period.…”
