Solar Activity Report for 3/8/03
- The sunspot number has edged up above 200 this evening for the first
time in a while, and there are now five numbered sunspot regions
visible. So far, the only that looks to have and real flare-producing
potential is region 296. That could change, however, so stay tuned.
The solar wind speed looks to be taking a bit of a respite from the
high speed profile it has exhibited of late, and the speed is down in
the low 400's for the time being. While aurora weren't widespread,
there were some quite beautiful aorora spotten in Alaska and Canada
during the period of March 3-5. See this link for some great aurora
There is another coronal hole just now rotating into view of the
eastern limb of the solar disk. It's not in view enough to see what
it's really like quite yet, but look for the possibility of another
round of high speed solar wind in about a week.
