Solar Activity Report for 5/14/04
- View SourceSunspot region was practically invisible a couple of days ago. Now,
it is naked-eye visible, and spans several Earth diameters end-to-end.
A new sunspot region, region 613, has also rotated into view. The
background X-ray flux has exhibited a slow but steady rise, and region
609 has recently started exhibiting signs that it could be capable of
generating a significant flare. Nothing yet, but stay tuned over the
next several days.
