THEO-007

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!

Agreed. I'll be keeping my eye on this one as well.

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?

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.

See ya
