Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 179 Issued at 2200Z on 28 Jun 2010
IA.  Analysis of Solar Active Regions and Activity from  27/2100Z
to 28/2100Z:  Solar activity has been very low. Region 1084 (S19E46)
was quiet and stable. No flares were observed during the period.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 27/2100Z to 28/2100Z:
The geomagnetic field has been predominately quiet with an isolated
unsettled period at 27/0300-0600Z.  Observations from the ACE
satellite indicate the continuation of a high speed solar wind
stream, with wind speeds at about 525km/s during the period.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled on days one and two (29-30 June). 
Quiet to unsettled conditions with isolated active periods are
expected on day three (01-July).
