First X-flare of the New Solar Cycle

From SpaceWeather.com:
MAJOR FLARE: Earth-orbiting satellites have detected the strongest solar flare in more than four years. At 0156 UT on Feb. 15th, giant sunspot 1158 unleashed an X2-class eruption. X-flares are the strongest type of x-ray flare, and this is the first such eruption of new Solar Cycle 24. The explosion that produced the flare also sent a solar tsunami rippling through the sun's atmosphere and, more importantly, hurled a coronal mass ejection toward Earth. This raises the possibility of geomagnetic storms in the days ahead. Visit Space Weather for images and updates.

What I would like to see is a history of X-class flares. How they they are related to solar activity maximum progression. Well Cycle 24 had somewhat of a slow start. Now the question of course is, how quickly will it increase in terms of activity to still somehow reach maximum in 2012. That is hwy it would be interesting to correlated the sun activity of the coming month with historical progression of previous cycles. I would assume that cycle 24 will present us with unprecedented anomalies. What's your best guess.. ?

Welcome to the playground Thomas and thank you for the idea for a posting.

I will try to post an answer to your question within the next week. Providing my computer doesn't die on me again.
