For the second day in a row, an active region on the far side of the sun is exploding and hurling CMEs into space. Watch the video below:


Today's eruption was almost as dramatic as yesterday's, and suggests that more eruptions are in the offing.

These explosions are occurring almost directly beneath NASA's STEREO-B spacecraft. An onboard telescope has recorded bright flashes of extreme UV radiation and shadowy shock waves emanating from the blast site. The telescope has also pinpointed the source: It is located just over the sun's eastern limb. Solar rotation is turning the region toward Earth, so geo-effective solar activity could commence within days. Stay tuned.
