Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 246 Issued at 2200Z on 02 Sep 2008

IA. Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity was very low. The visible solar disk remains spotless.

IB. Solar Activity Forecast: Solar activity is expected to remain very low.

IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field was quiet.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet on Day 1 (3 Sep). Unsettled to active conditions are expected on Days 2-3 (4-5 Sep), with a slight chance of isolated minor storm periods at high latitudes, as a recurrent coronal hole becomes geoeffective.
