Solar Activity Report for 2/22/03
- The high speed solar wind is continuing, and doing so longer than I
would have thought. The solar wind speed has been elevated since the
15th, although geomagnetic activity has been mostly subdued, save for
a couple of aurora outbreaks in Alaska. I honestly don't know how
long the high speed solar wind will last. There is another small
coronal hole that is coming into an Earth-pointing position, and the
high speed solar wind from it should be arriving on or about the 26th.
Therefore, the solar wind speed could stay elevated for several more
days. There are only two numbered sunspot regions visible tonight,
and the sunspot number is correspondingly low. However, one of those
sunspot regions, region 290, has at least an outside chance of
producing an M-class flare.
