Sažetak
A sample of 211 front-sided, flare-associated CMEs, having a minimal speed of 400 km/s, were randomly selected from the LASCO/SOHO catalog and associated with a disturbance storm time (Dst) index. This sample includes geoeffective, non-geoeffective and CMEs which missed the Earth. The latter was derived using the in-situ data and CME-ICME-Dst list made by Richardson&Cane (2010). Statistical analysis is employed to detect relationships between CME parameters, flare parameters and the Dst value. The influence of “CME trains” is also investigated. We present the results of the statistical analysis, which will be used to make an empirical model for the predictions of geomagnetic activity based on the remote sensing of CMEs using L1 coronagraph. This work has received funding from the European Commission FP7 Project COMESEP (263252).
