Sunspot-reversed-0.jpgSunspot-905: a sign of an incoming new "Solar Cycle"? (1)59 visiteDa "NASA - Picture of the Day" del 30 Agosto 2006:"Why is sunspot-905 backwards? Perhaps it is a key marker for the beginning of a new Magnetic Cycle on our Sun.
Every 11 years, our Sun goes through a Magnetic Cycle, at the end of which its overall magnetic orientation is reversed. An 11-year Solar Cycle has been observed for hundreds of years by noting peaks and valleys in the average number of sunspots.
Just now, the Sun is near Solar Minimum, and likely to start a long progression toward the most active time, called Solar Maximum, in about 5,5 years".
