that's indeed so amazing! until yesterday I was in a "wait and see" position and I thought "ok, they were wrong, all I can see is a prety beautiful wheather for this season". I I met this person who flew this morning from germany and he told me there are storms in the north (I'm actually in southern france)! I can imagine predicting weather from past solar activity pattern, I do not see how it is possible to predict solar erruptions though!
