SDF Number 041 Issued at 2200Z on 10 Feb 2004

IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z

Solar activity has been very low. Regions 551 (S08W41) and 554 (S10E38) have produced numerous B class flares. No significant changes were observed to regions on the visible disk. No new regions were numbered.
IB. Solar Activity Forecast
Solar activity is expected to be low. Regions 551 and 554 may produce C- and isolated M-class flares.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field has been quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels, with active and minor storm conditions possible on 12 and 13 November as a coronal hole high speed solar wind stream moves into geoeffective position.
