Cycle 24 Prediction

This is the prediction by Dr Hathaway - where the solar maximum is expected to occur around 2013. Like all predictions it can be wrong. It should be noted however, that there was a coronal mass ejection event in 1989 (which was not at a maximum) which knocked out power in all of the province of Quebec - see blog post below about the great storm of 1859. A co-worker told me of a similar event in 2003 which knocked out power in New York State.
