Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 245 Issued at 2200Z on 01 Sep 2008
IA. Analysis of Solar Active Regions and Activity from 31/2100Z to 01/2100Z: Solar activity was very low. The visible solar disk remained spotless.
IB. Solar Activity Forecast: Solar activity is expected to remain very low.
IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to remain quiet for days one and two (2-3 Sep), becoming quiet to unsettled by day three (4 Sep) in response to an approaching recurrent coronal hole high speed stream.
