[glow=black,5,900]BACKWARD SUNSPOT:[/glow]
Evidence continues to mount that the next solar cycle (Solar Cycle 24) is beginning. For the second time in a month, a backward sunspot has appeared. The first backward spot, sighted on July 31st, was tiny and fleeting. The latest, however, is big and sturdy, bipolar sunspot 905:

"Backward" means magnetically backward. Compared to how sunspots have been during the past 11-year solar cycle, the north and south magnetic poles of sunspot 905 are reversed. This is what happens when one solar cycle gives way to another--sunspots reverse polarity.
The onset of Solar Cycle 24 is big news, because the cycle is expected to be intense, but don't expect any big storms right away. Solar cycles take years to ramp up to full power. The next Solar Max is expected in 2010.
