Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 166 Issued at 2200Z on 15 Jun 2010
IA.  Analysis of Solar Active Regions and Activity from  14/2100Z
to 15/2100Z:  Solar activity was very low.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low for the next 3 days (16-18 June).
IIA.  Geophysical Activity Summary 14/2100Z to 15/2100Z:
The geomagnetic field was quiet to unsettled with an isolated minor
storm period at high latitudes from 0900-1200Z.  An increase in
solar winds speed to 540 km/s was observed at ACE late in the day.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be mostly unsettled to active with a slight chance for
an isolated period of minor storming on day 1 (16 June) due to
coronal hole effects. Conditions are expected to be quiet to
unsettled with a chance for active conditions on day 2 (17 June) and
mostly quiet conditions are expected on day 3 (18 June).
