Sažetak
We analyse several selected CME events using ultraviolet and coronagraphic images from spacecraft at different vantage points (SDO, SOHO, STEREO-A and STEREO-B). We perform a 3D reconstruction of both the flux rope and shock of the events using the Graduated Cylindrical Shell (GCS) model and calculate CME kinematic parameters (velocity, acceleration). Next, we fit the obtained results with empirical models describing the expansion of CMEs in the heliosphere and compare them with in situ measurements. Finally, we relate selected events with decreases in the Galactic Cosmic Ray Flux, known as Forbush decreases, detected by near- Earth spacecraft (SOHO/EPHIN) and terrestrial detectors (neutron monitor), and perform the analysis using the analytical diffusion- expansion Forbush decrease model ForbMod.
