Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 168 Issued at 2200Z on 16 Jun 2008
IA. Analysis of Solar Active Regions and Activity from 15/2100Z to 16/2100Z: Solar activity was very low. New Region 999 (S02E60), an Axx Alpha group, was numbered today.
IB. Solar Activity Forecast: Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic field was quiet to unsettled. The increase in activity is due to a coronal hole high speed stream.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled, with a slight chance of active to minor storm conditions at high latitudes.
