Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 066 Issued at 2200Z on 07 Mar 2006

IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity was very low. Region 856 (S08W38) produced a long-duration B2 flare at 07/1558Z. A six degree disappearing filament, centered at N02E24, was reported between 06/1000Z and 06/2255Z.

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

IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field was quiet to active. Active conditions occurred from 07/0000Z to 07/0600Z as a result of a prolonged period of southward IMF Bz.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for the next 24 hours. On 09-10 March, predominantly unsettled conditions are expected, with possible isolated active periods. This increased activity is due to a high speed coronal hole stream.
