Solar Activity Report for 10/12/03
- The level of geomagnetic activity has picked up a little since my last
report, although it could hardly be lower, could it? The solar wind
speed has actually dropped into the lower 300's, but the
Interplanetary Magnetic Field has been dipping into a south-pointing
orientation, which has increased the geomagnetic activity to the
unsettled category. The solar wind speed is expected to increase in
48 - 72 hours as the Earth moves into a high speed solar wind stream
coming from something of donut-shaped coronal hole. None of the three
small sunspot regions visible look to have the potential for
generating a significant flare at this time.
The current solar and geomagnetic conditions are :
NOAA sunspot number : 93
