Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 092 Issued at 2200Z on 02 Apr 2006

IA. Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity was very low. Region 865 (S11W06) continues to show an increase in area and remains a beta gamma delta magnetic configuration. New Region 867 (S16E16) was numbered today.

IB. Solar Activity Forecast: Solar activity is expected to be very low to low. Isolated C-class flares are possible from Regions 865 and 867.

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 to unsettled on 03 and 04 April. On 05 April, mostly quiet to unsettled conditions are expected with isolated active periods possible as a coronal hole high speed stream becomes geoeffective.
