Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 069 Issued at 2200Z on 09 Mar 2004

IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z

Solar activity has been low. Region 570 (S14E34) has produced numerous B- and C-class flares, including a C1.3/Sf at 09/0648 UTC. No significant development was observed from regions on the visible disk, and no new regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be low. Region 570 may produce C- and isolated M-class flares.
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
The geomagnetic field has been at quiet to minor storm levels. Increased activity is most likely due to the effects of a co-rotating interaction region interacting with Earth's magnetic field. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be unsettled to active, with occassional minor storm conditions from the effects of high speed solar wind as a coronal hole moves into geoeffective position.
