On space weather prediction

One of the important tasks of space weather prediction is to forecast the arrival of sub– cosmic ray particles and the onset/intensity of geomagnetic storms after solar flares. For these purposes, it is necessary to predict the onset/intensity of solar flares, to track the transit (or propagation) of coronal mass ejections (CMEs) in interplanetary space and finally to estimate the power (erg/s or w) produced by the interaction between CMEs and the magnetosphere. I find that a much more integrated and coordinated effort is needed than in the past in advancing the present space weather prediction. A few suggestions are provided for this purpose.
