Sunspot-reversed-1.jpgSunspot-905: a sign of an incoming new "Solar Cycle"? (2)55 visiteDa "NASA - Picture of the Day" del 30 Agosto 2006:"An indicator that the Sun's magnetic field is reversing is the appearance of sunspots with the reverse magnetic polarity.
A few weeks ago, one small candidate "reverse sunspot" was sited but faded quickly. Now, however, a larger sunspot with negative polarity is being tracked. This sunspot, numbered 905, appears as the unusual white spot in the above magnetic image of the Sun taken with the SOHO spacecraft a few days ago. In the past few days, Sunspot-905 has actually begun to break apart and might also become the source of coronal mass ejections and explosive solar flares.
Solar astronomers predict that the coming Solar Maximum will be unusually active".
