Solar Activity Report for 11/22/05
- CRAP! I had no idea it had been so long since I posted one of these.
I really need to do this more regularly. Sorry about that, folks.
There's been some good stuff happening, too.
Sunspot region 822 came on the scene, and fired off a series of
M-class flares over the course of several days. None of them were of
the long-duration variety, however, and no strong CME's were observed.
Likewise, there wasn't any significant geomagnetic activity
associated. At the present time, sunspot region 822 is still there,
and is big enough to be naked eye visible. It has, however, decreased
in magnetic complexity, although there is still a slight chance for
another M-class flare. There's a small coronal hole that has rotated
into an Earth-pointing position, and we could see some mild solar wind
gusts from it starting tomorrow.
There's one thing visible now that I believe is noteworthy. It's
sunspot region 823. In and of itself, it's quite unremarkable. What
is interesting is where it is. As a sunspot cycle progresses,
sunspots make a steady progression from occurring at about 30 degrees
latitude to almost at the solar equator. Sunspot regions 822 and and
824 are very close to the equator. So where is region 823? At about
30 degrees latitude. There is always some overlap from one sunspot
cycle to the next, and it is common to see sunspots appearing at the
higher latitudes at the same time you see others near the equator.
What's interesting is that this is the first one I've seen in a long,
long time at such a high latitude. Is this first sign of Cycle 24
getting ready to start? Time will tell, but it is getting to be about
the time one would expect to see it. Stay tuned!!
