Solar Activity Report for 9/23/04
- Things have quieted since the geomagnetic storm conditions that
existed when I made my last report. Barring anything unexpected, it
should stay that way for the next two or three days. Of the two
sunspot regions visible now, regions 672 and 673, neither look to have
the potential for generating a significant flare at this time. There
is a diffuse coronal hole that has rotated into an Earth-pointing
position. The majority of it is well into the sun's northern
hemisphere, but a portion of it extends down towards the solar
equator. We could get a few puffs of solar wind from it along about
