Thanks a lot guys

,
I understand it a little bit better now as i had no idea what plages were until now thanks for that.
I would think that the corona would be cooler than the photsphere but i have now read up on it and it is infact very hot ranging from 1 million k to 5 million k.Thats hot

.
But why ?Why is the corona so hot?
Craig-On your last point about keeping fact away from belief I agree with you but I think you misunderstood me what i meant to say is that I THINK (not believe) that it is anthropogenic but there may be other factors aswell.
Good point Paddy
