Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 170 Issued at 2200Z on 18 Jun 2008
IA.  Analysis of Solar Active Regions and Activity from  17/2100Z
to 18/2100Z:  Solar activity was very low. Region 999 (S03E37)
remains stable.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 17/2100Z to 18/2100Z:
The geomagnetic field was quiet to unsettled due to a coronal hole
high speed stream. The greater than 2 MeV electron flux at
geosynchronous orbit reached high levels today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled for days one and two (19-20 June),
returning to quiet levels on day three (21 June) as the high speed
stream subsides.
