2012: Solar Flares
Planet Niburu is not the only thing predicted to happen in 2012:
"Solar cycle 24 just got started a few days back. The sun announced it with a major solar flare (Big Flare Portends Beginning of Solar Cycle 24).
Solar flares rise and fall on an 11-year cycle, and last year marked what scientists thought was the solar minimum. But through the beginning of 2009, the sun stayed unusually quiet. That changed yesterday, when a major sunspot appeared on the backside of the sun, where it was captured by NASA’s STEREO instrument.
“This is the biggest event we’ve seen in a year or so,” said Michael Kaiser, research scientist with the heliophysics division at NASA Goddard Space Flight Center. “Does this mean we’re finished with the minimum or not? It’s hard to say. This could be it. It’s got us all excited.”
People have been counting sunspots since Galileo first observed one in the early 17th century. Through the 28 cycles that have been well-documented, stretching from 1745 to today, the average cycle length has been 11 years, but shorter and longer cycles have been observed. (The polarity of solar storms also alternates, so technically, a full cycle is 22 years.)
For unknown reasons, the current solar minimum has lasted longer than normal. “It’s been a long solar minimum, the longest and deepest one through the last hundred years, but not out of the extreme ordinary,” Kaiser said.
The next solar maximum is in 2012."
