The causes of geomagnetic disturbances are either high velocity streams of solar wind originating in coronal holes or coronal mass ejections related to solar energetic events. In this presentation we will concentrate on the second case. Data concerning solar energetic events, published by the USAF/NOAA in the form of daily reports, have been collected since 1996. An analysis of ten years long data collection has shown that the degree of the geoeffectiveness of energetic events depends not only on their size and on their solar disc location but also on the fact whether the events are associated with type II and IV radio bursts.
