Summary
| Description | A pair of dynamic active regions rotated into view as SDO caught the activity over for a little over two days (Aug. 15 -- 17, 2011). One can compare the activity in this side-by-side-by-side video clip in three wavelengths. At left, plasma near the surface is shown at 60,000 degrees in extreme ultraviolet light. Note that the feature rising up above the Sun's edge between the active regions is a quiescent prominence. The middle portion with many looping arcs, also in extreme UV light, shows plasma heated to about a million degrees. The right portion shows the magnetically intense sunspots themselves that are the sources of all the activity. These areas have produced smaller solar storms and could yet generate stronger ones. Time will tell. |
