Possible Large Solar Cycle 24 Sunspot Group

[Thomas F. Giella NZ4O]

During last weeks propagation forecast I said,"Recurrent sunspot group #11115 will rise above the eastern limb of the Sun on Thursday-Friday 05/07-08/2009, if it survived transit on the back side of the Sun."

It looks as though #11115 has survived. It remains to be seen whether it will be classified as recurrent #11115 or new #11117.

THE SUN IS STIRRING: NASA's STEREO-B spacecraft is monitoring an active region hidden behind the sun's eastern limb. On May 5th, it produced an impressive coronal mass ejection (CME, movie) and a burst of Type II radio emissions caused by a shock wave plowing through the sun's outer atmosphere. STEREO-B's extreme UV telescope captured this image during the explosion:

At the root of all this activity is probably a sunspot. Its high latitude identifies it as a member of new Solar Cycle 24. The putative sunspot is not yet visible from Earth, but the sun is turning the region toward us for a better view. Readers with solar telescopes should keep an eye on sun's northeastern limb for an emergence on May 7th or 8th.
