Active region #1429, the source of several major flares, CMEs, and radio blackouts earlier this month, has made it all the way around the sun. The STEREO spacecraft followed it across the far side, and now it is just becoming visible on the limb. It is still flaring regularly, and producing large CMEs which are only marginally geoeffective at this point.
Expect daily solar fluxes to rise out of the 100 range, and K indices to approach the event threshold as this region continues its movement across the disk, and as a full-halo CME from another region on March 27 UTC approaches our planet. In addition, C class flares are likely, and M class is not out of the question.
