Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 227 Issued at 2200Z on 15 Aug 2009
IA.  Analysis of Solar Active Regions and Activity from  14/2100Z
to 15/2100Z:  Solar activity was very low. No flares were observed.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 14/2100Z to 15/2100Z:
Geomagnetic field activity was at quiet levels.
IIB.  Geophysical Activity Forecast:  Geomagnetic field activity is
expected to be at quiet levels during days 1 – 2 (16 – 17 August).
Activity is expected to increase to unsettled levels on day 3 (18
August) as a recurrent coronal hole high-speed stream begins to
disturb the field.
