Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 165 Issued at 2200Z on 13 Jun 2008
IA. Analysis of Solar Active Regions and Activity from 12/2100Z to 13/2100Z: Solar activity was at very low levels. Region 998 (S10E12) decayed slightly in area from 30 millionths to 20 millionths during the summary period.
IB. Solar Activity Forecast: Solar activity is expected to remain at very low levels.
IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic field was at quiet levels.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to remain at quiet levels for days one and two (14 and 15 June) of the forecast period. Conditions are expected to increase to quiet to unsettled levels with a slight chance of isolated active periods on day three (16 June) due to a coronal hole high speed stream rotating into a geoeffective position.
