Calculation of ICME arrival times

Main reference

This model is based on the article "Propagation of Interplanetary Coronal Mass Ejections: The Drag-Based Model" (Vrsnak et al. 2012).

Gamma drag parameter; usually between 0.2 and 2 (10-7 km-1):
Rs: distance where the CME speed is measured (solar radii): (Preferentially near 20 Rs.)
v0; speed of CME Rs, (km/s):
w; background solar wind speed (km/s):
Date and time of CME at the given Rs:
