Solat Activity Report for 9/11/04
- There hasn't been any activity to speak of since my last report, that
is until just a little while ago. As I write this, there is a
long-duration M-class flare in progress. It looks to be about an M-5
or so. There's no official word of the origin of the flare yet, but I
suspect that it came from sunspot region 672, which has recently
emerged over the eastern limb of the solar disk. Analysis of the SOHO
satellite coronagraph imagery over the next day or two will tell
whether or not there is a CME from the flare headed our way. Stay tuned.
