Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 247 Issued at 2200Z on 03 Sep 2008
IA. Analysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: Solar activity was very low. No flares occurred during the past 24 hours. The solar disk continues to be spotless.
IB. Solar Activity Forecast: Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic field was mostly quiet during the past 24 hours. Solar wind signatures at ACE indicated the passage of a corotating interaction region followed by a slow steady rise in solar wind velocity.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly unsettled with occasional active periods for the next two days (4-5 September) due to the influence of a favorably positioned coronal hole. Activity levels are expected to decline to predominantly unsettled for the third day (6 September).
