Sažetak
Coronal Mass Ejections (CMEs) are known to cause geomagnetic storms on Earth. However, not all CMEs will trigger geomagnetic storms, even if they are heading towards the Earth. In this study, frontside halo CMEs with speed larger than 800 km/s have been identified from the SOHO LASCO catalogue. A subset of these halo CMEs did not cause a geomagnetic storm the following four days and have therefore been considered as false alarms. The properties of these events are investigated and discussed here. The ability to identify potential false alarms is considered as an important factor when forecasting geomagnetic storms. This work has received funding from the European Commission FP7 Project COMESEP (263252)
