FARSIDE SUNSPOT: NASA’s STEREO-B spacecraft is tracking an active region over the sun’s eastern horizon that could be a large, new-cycle sunspot. We can’t yet see it from Earth, but the sun’s rotation is turning the region toward us, and it could pop into view as early as Sept. 21st. Readers with solar telescopes should monitor the sun’s eastern limb for developments. Images and updates may be found at
