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) and a burst of radio emissions signalling the passage of a shock wave through the sun's outer atmosphere. Activity has continued apace today, May 6th, with at least two more eruptions. The blast site is not yet visible from Earth, but the sun is turning the region toward us for a better view. Is a new-cycle sunspot in the offing? Readers with solar telescopes could see it emerge as early as May 7th or 8th. Visit http://spaceweather.com for images, movies and updates.
