Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 159 Issued at 2200Z on 07 Jun 2008
IA.  Analysis of Solar Active Regions and Activity from  06/2100Z
to 07/2100Z:  Solar activity was very low. No flares were detected.
The visible disk remained spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z:
Geomagnetic field activity ranged from quiet to unsettled levels. ACE
solar wind data indicated the unsettled levels were due to increased
solar wind velocities and IMF changes associated with a solar sector
boundary crossing at around 07/0900Z (away to toward orientation).
Velocities reached a peak of 551 km/sec at 07/1604Z, then gradually
decreased. IMF changes included increased Bt (peak reading 10 nT at
07/0856Z) and mostly southward Bz after 07/0530Z (minimum -7 nT at
07/0652Z).
IIB.  Geophysical Activity Forecast:  Geomagnetic field activity is
expected to be at mostly quiet levels through the period (08 - 10
June).
