Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 210 Issued at 2200Z on 29 Jul 2006

IA. Analysis of Solar Active Regions and Activity from 28/2100Z to 29/2100Z: Solar activity was very low.

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

IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic field was mostly quiet.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet on 30 July. On 31 July through 01 August, a coronal hole high speed stream is expected to move into geoeffective position causing unsettled to active conditions with minor storm periods possible.
