Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 153 Issued at 2200Z on 02 Jun 2005

IA. Analysis of Solar Active Regions and Activity from 01/2100Z
to 02/2100Z: Solar activity was very low. Region 772 (S17E23)
continues to show a modest amount of magnetic complexity.

IB. Solar Activity Forecast: Solar activity is expected to be low.
There is a good chance of C-class activity from Region 772.

IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z:
The geomagnetic field was quiet to mildly unsettled. The energetic
electron flux at geosynchronous orbit was high again today.

IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled through 05 June.
