SOLAR CYCLE 24: Solar physicists have been waiting for the appearance of a reversed-polarity sunspot to signal the start of the next solar cycle. The wait is over. A magnetically reversed, high-latitude sunspot emerged today: image. If you have a solar telescope, take a look at this important new active region. It marks the beginning of Solar Cycle 24 and the sun's slow ascent back to Solar Maximum. Magnetic Image Visible Light Image |

Finally, and I'm glad! Solar minimum is sooooo boring. I know it'll take a while for solar activity to gear up. By 2011/12 I will have a solar telescope (what's the point of buying one now?), and look forward to massive sunspots and raging CME's.

Finally, and I'm glad! Solar minimum is sooooo boring. I know it'll take a while for solar activity to gear up. By 2011/12 I will have a solar telescope (what's the point of buying one now?), and look forward to massive sunspots and raging CME's. Even when the Sun appears blank in visible light there is still a lot to see in H - alpha and other wavelengths. And more Sunspot strangeness reported on spaceweather.com: CURIOUS SUNSPOT: A new sunspot is emerging just south of the sun's equator, and it is a curious one. The spot's magnetic polarity is reversed compared to other nearby magnetic patches on the sun's surface. Reversed-polarity sunspots are signs of a new solar cycle and, indeed, Solar Cycle 24 began just last week. So far, so good. But this spot is near the equator. New-cycle spots are supposed to be at high latitudes--hence the curiosity. Is this a genuine new-cycle spot? A weird old-cycle spot? Image Link |
