Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 288 Issued at 2200Z on 15 Oct 2006
IA. Analysis of Solar Active Regions and Activity from 14/2100Z to 15/2100Z: Solar activity was very low. The solar disk remains spotless.
IB. Solar Activity Forecast: Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic field has been quiet to active. Solar wind speed has been decreasing throughout most of the day as the coronal hole rotates out of a geoeffective position.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for the next three days (16 – 18 October).
