THEO-007 10 Report post Posted July 25, 2009 44 degrees today in athens and very bad seeing to observe the sun. The SW network gives small spot plages around the two bigger plages. The active region 1024 coming again at eastern limb. No filaments on solar surface. SW CHROMOSPHERIC NETWORK Share this post Link to post Share on other sites
mattwastell 10 Report post Posted July 25, 2009 Thanks for sharing your images - spaceweather identified this region's magnetic polarity as a member of the old Solar Cycle 23. I am looking forward to the return of AR 1024 - it will be interesting to see how it has progressed after a lap. It has been the largest sunspot this year to date!

Radar 591 Report post Posted July 26, 2009 I am looking forward to the return of AR 1024 - it will be interesting to see how it has progressed after a lap. This is interesting. How long will it take to do one lap (I could google but for the sake of the thread I won't)? Am I right in saying that if AR1024 gets bigger that this is an indication of a new solar cycle?

mattwastell 10 Report post Posted July 28, 2009 Hi Ray I think it takes 10 days for things to return once they disappear over the limb. Different solar cycles are determined by the magnetic polarity of the sunspot - they flip and the new solar cycle officially begins. We are in solar cycle 24.
