Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 069 Issued at 2200Z on 10 Mar 2006

IA. Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity was very low. No flares have been observed over the past 24 hours.

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

IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field was quiet to unsettled.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for 11 March. Isolated active periods are possible due to a geoeffective coronal hole. Predominantly quiet conditions are expected for 12-13 March.
