Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 096 Issued at 2200Z on 06 Apr 2006

IA. Analysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: Solar activity increased to moderate levels. Region 865 (S11W60) produced two M-class flares today, an impulsive M1 event occurring at 06/0533Z and a second impulsive M1 event occurring at 06/2042Z. The remainder of the observed flare activity recorded during the period were B-class events. Region 865 underwent slight decay in sunspot area (530 millionths). This region continues to depict a beta-gamma magnetic structure. Region 869 (S12E24) was numbered today.

IB. Solar Activity Forecast: Solar activity is expected to be at low to moderate levels. Region 865 has the potential for the production of further impulsive M-class flare activity.

IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic field ranged from quiet to active levels. A sustained period of southward Bz was followed by active conditions between 06/0900-1200Z.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at predominantly unsettled levels on 07 and 08 January. Isolated active to minor storm conditions are expected on 09 January due to a recurrent transequatorial coronal hole high speed stream..

III. Event Probabilities 07 Apr-09 Apr
