Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 075 Issued at 2200Z on 16 Mar 2006
IA. Analysis of Solar Active Regions and Activity from 15/2100Z to 16/2100Z: Solar activity continues at very low levels. There are just a couple of small, insignificant sunspot groups on the visible disk.
IB. Solar Activity Forecast: Solar activity continues at very low levels.
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled on 17 and 18 March. A high speed coronal hole stream is expected to become geoeffective on 19 March, and produce isolated active to minor storm conditions.
