Solar Activity Report for 1/13/03
- The solar wind speed has declined after the most recent coronal hole
encounter. No significant geomagnetic activity resulted from it.
There are seven numbered sunspot regions visible tonight. None look
to have any real flare producing potential right now, but there is at
least an outside chance for one. The most interesting news may be
what's on the way. The massive plume in this picture erupted from a
source that is located over the eastern limb of the solar disc.
It will be interesting to see what shows up in a few days. Oh, and by
the way, take a look at this one, too. The blue dot represents Earth.
