Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 211 Issued at 2200Z on 30 Jul 2006

IA. Analysis of Solar Active Regions and Activity from 29/2100Z to 30/2100Z: Solar activity continued at very low levels again today. New Region 902 (S10W21) was numbered today.

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

IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic field was quiet.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to range from unsettled to active conditions with minor storm periods possible. This activity is due to a coronal hole high speed stream moving into a geoeffective position during the forecast period (31 Jul to 02 Aug).
