Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 068 Issued at 2200Z on 09 Mar 2006

IA. Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity was very low. No flares occurred during the past 24 hours.

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

IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field was mostly quiet.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for 10-11 March. Isolated active periods are possible during this time, due to a favorably positioned coronal hole. Predominantly quiet conditions are expected on 12 March.
