Solar Activity Report for 12/23/03
- All is quiet this evening. The recent coronal hole solar wind stream
encounter pretty much turned out to be a non-event. A persistent
north-pointing interplanetary magnetic field kept the geomagnetic
activity suppressed. While the solar wind speed is still mildly
elevated, I don't expect to see any effects from it. If we do see
anything noteworthy, it might be in the form of a flare from either
sunspot region 525 or 528. They are both have at least an outside
chance of generating an M-class flare.
