Sunspot 1039 is still on the far side of the solar disc, as observed from Earth, but 1039 is providing scientists with promise of continued activity. NASA’s STEREO-B Spacecraft can “see” regions of Sun that are not yet visible from Earth. What STEREO-B has detected are two eruptions from the 1039 active areas.
The active regions will appear along the eastern solar limb within a week as Sunspot 1039 rotates into view. If you want to see the video of the eruptions, spaceweather.com has it and more information posted.
