Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 067 Issued at 2200Z on 08 Mar 2007

IA. Analysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: Solar activity was very low. The visible solar disk remains spotless. There were no flares during the past 24 hours.

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

IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z:

The geomagnetic field has been quiet to unsettled. The greater than

2 MeV electron flux at geosynchronous orbit reached high levels again today.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet for the next three days.
