SDF Number 328 Issued at 2200Z on 24 Nov 2006

IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z

Solar activity was at very low levels. The visible disk is currently spotless.
IB. Solar Activity Forecast
Solar activity is expected to remain at very low levels.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
The geomagnetic field was at quiet to minor storm levels. A favorably positioned recurrent high speed coronal hole stream was responsible for the elevated conditions.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to active levels. A return to predominantly quiet levels is expected on 27 November as the coronal hole rotates out of geoeffective position.
